  • Work in a well-ventilated area.
  • Work with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
  • Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth or eyes or to lie on the skin may promote absorption of harmful chemicals.

SAFETY RULES FOR CORDLESS LAWN MOWER

DANGER
This machine was built to be operated according to the rules for safe operation included in this manual. As with any type of power equipment, carelessness or error on the part of the operator can result in serious injury. This machine is capable of amputating hands and feet and throwing objects. Failure to observe all safety instructions could result in serious injury or death.

WARNING
When using electric lawn mowers, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury. These basic precautions include the following:

Children
Tragic accidents can occur if the operator is not alert to the presence of children.

Children are often attracted to the mower and mowing activity. They do not understand the dangers. Never assume that children will remain where you last saw them.

• Keep children out of the mowing area and under the watchful care of a responsible adult other than the operator.
• Be alert and turn the mower off if a child enters the area.
• Use extreme care when approaching blind corners, doorways, shrubs, trees, or other objects that may obscure your vision of a child who may run into the mower.
• Never allow children under 14 years old to operate a power mower. Children 14 years old and over should read and understand the operation instructions and safety rules in this manual and should be trained and supervised by a parent. Only responsible individuals who are familiar with these rules of safe operation should be allowed to use this machine.

Operation

General Operation:

• Read this operator’s manual carefully in its entirety before attempting to assemble this machine. Read, understand, and follow all instructions on the machine and in the manuals before operation. Be completely familiar with the controls and proper use of this machine before operating it. Keep this manual in a safe place for future and regular reference.
• Use the right appliance – Do not use the lawn mower for any job except that for which it is intended. Your lawn mower has been designed to perform only one job: to mow grass.
• Don’t overreach – Keep proper footing and balance at all times.
• Objects struck by the lawn mower blade can cause severe injuries to persons. The lawn should always be carefully examined and cleared of all objects prior to each mowing.
• Keep the area of operation clear of all persons, particularly small children, and pets.
• Before and while moving backwards with the mower, look behind and down for small children and other people.
• Keep clear of the discharge opening at all times.
• This machine is a precise piece of power equipment, not a plaything. Therefore, exercise extreme caution at all times. Your unit has been designed to perform one job: to mow grass. Do not use it for any other purpose.
• Don’t force the lawn mower – it will do the job better and more safely at the rate for which it was designed.
• Thoroughly inspect the area where the equipment is to be used. Remove all stones, sticks, wire, toys and other foreign objects that could be tripped over or picked up and thrown by the blade. Thrown objects can cause serious personal injury.
• Plan your mowing pattern to avoid discharge of material toward roads, sidewalks, bystanders and the like. Also, avoid discharging material against walls or obstructions, which may cause discharged material to ricochet back toward the operator.
• To help avoid blade contact or an injury from thrown objects, stay in the operator zone behind the handles and keep children, bystanders, helpers and pets at least 100 feet (30m) from the mower while it is in operation. Stop the machine if anyone enters the area.
• Always wear safety glasses or safety goggles during operation and while performing an adjustment or repair to protect your eyes. Thrown objects that ricochet can cause serious injury to the eyes. Always use a face or dust mask if the operation is dusty.
• Dress properly – Do not wear loose clothing or jewelry. They can be caught in moving parts. Use of rubber gloves and footwear is recommended when working outdoors. Wear sturdy, rough-soled work shoes and close-fitting slacks and shirts. Shirts and pants that cover the arms and legs and steel-toed shoes are recommended. Never operate this machine in bare feet, sandals, slippery or lightweight (e.g., canvas) shoes.
• Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade can amputate hands and feet.
• A missing or damaged discharge cover can cause blade contact or injuries from thrown objects.
• Many injuries occur as a result of the mower being pulled over the foot during a fall caused by slipping or tripping. Do not hold onto the mower if you are falling; immediately release the handle.
• Never pull the mower back toward you while you are walking. If you must back the mower away from a wall or obstruction, first look down and behind you to avoid tripping, and then follow these steps:
  • Step back from mower to fully extend your arms.
  • Be sure you are well balanced with sure footing.
  • Pull the mower back slowly, no more than half way toward you.
  • Repeat these steps as needed.
• Do not operate the mower while under the influence of alcohol or drugs.
• Stay alert – watch what you are doing. Use common sense. Do not operate the lawn mower when you are tired.
• The motor/blade control handle is a safety device. Never attempt to bypass its operation. Doing so makes the safety device inoperative and may result in personal injury through contact with the rotating blade. The motor/blade control handle must operate easily in both directions and automatically return to the disengaged position when released.
• Avoid dangerous environments – Don’t use lawn mowers in damp or wet locations so as to avoid slipping and falling during operation.
• Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your footing, release the motor/blade control handle immediately and the blade will stop rotating within three seconds.
• Mow only in daylight or good artificial light. Walk, never run while operating.
• Stop the blade when crossing gravel drives, walks or roads.
• If the equipment should start to vibrate abnormally, immediately stop the motor, remove the battery and check for the cause. Vibration is generally a warning of trouble.
• Never operate the mower without the proper trailing shield, discharge cover, grass bag, mulching insert, side discharge chute, motor/blade control handle or other safety protective devices in place and working. Never operate the mower with damaged safety devices. Failure to do so can result in personal injury.
• Always stop the motor before making adjustments to a wheel or a cutting-height adjustment.
• If situations occur that are not covered in this manual, use care and good judgment. Contact SKIL Customer Service for assistance.
• Use only the charger supplied by the manufacturer to recharge.
• Do not charge the battery pack outdoors.
• Do not charge the battery pack in rain or in wet locations.
• Use the lawn mower only with specifically designated battery pack. Use of any other batteries may create a risk of fire.
• Use only with battery packs and chargers listed below.

Operation On A Slope:
Slopes are a major factor related to slip-and-fall accidents, which can result in severe injury. Operation on slopes requires extra caution. If you feel uneasy on a slope, do not mow it. For your safety, use the slope gauge in this manual to measure slopes before operating this unit on a sloped or hilly area. If the slope is greater than 15 degrees, do not mow it.

Do:

• Mow across the face of slopes; never mow up and down. Exercise extreme caution when changing direction on slopes.
• Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you to slip or trip. Tall grass can hide obstacles.

Do not:

• Do not mow near drop-offs, ditches or embankments; you could lose your footing or balance.
• Do not mow slopes greater than 15 degrees, as shown on the slope gauge.
• Do not mow on wet grass. Unstable footing could cause slipping.

Self-Propel System (model SM4910-00 only)
The SM4910-00 mower is equipped with self-propel function. This system is independent of the blade On-Off switch and it is not dependent on blade rotation. For example, when you have completed cutting your lawn, you can use the self-propel to propel the mower back to your storage location without blade rotation. You may also choose to operate the mower as a non-self- propelled mower to maximize battery running time.

To operate the self-propel system without blade rotation, pull the self-propel lever to the handle.

To turn the self-propel off, release the self-propel trigger (Fig. 15). The system has a speed-adjustment knob. Rotate the knob to adjust the mower self- propel speed according to your need.

To operate with the blade rotating for cutting:

1. Depress the safety button.
2. With the safety button depressed, pull the bail switch upward to the handle and release the safety button.
3. Hold the bail switch against the handle with one hand. Pull the self-propel lever to the handle with the other hand.
4. With one hand, hold both the bail switch and the self-propel lever against the handle and use the other hand to adjust the self-propel speed adjustment knob to choose the desired speed.

• NOTICE: When you turn off the self-propel, for example, at the end of a row, it may become temporarily locked if you pull backwards on the mower. Simply push ahead slightly and then move the mower as required.
• NOTICE: During cutting, at times it may be easier to mow around an object, with the self-propel turned off.

WARNING
To reduce the risk of injury, never attempt to override the operation of the switch or self-propel system. Use the self-propel for its intended purpose only.

Mowing Tips

NOTICE:
A sharp blade will greatly enhance the performance of the mower, especially when cutting tall grass. Make sure to check the sharpness of the blade before mowing.

• Verify that the lawn is free of stones, sticks, wires, and other objects which could damage the lawn mower or motor. Such objects could be accidentally thrown by the mower in any direction and could cause serious personal injury to the operator and to others.

WARNING
If you strike a foreign object, stop the motor and remove the battery. Thoroughly inspect the mower for any damage, and repair the damage before restarting and operating the mower. Excessive vibration of the mower during operation is an indication of damage. The unit should be promptly inspected and repaired.

• For best results, do not mow in circles. Travel back and forth across the lawn.
• When cutting thick grass, reduce your walking speed in order to allow for a more effective cut and a proper discharge of the clippings.
• To maintain a healthy lawn, cut off only one-third or less of the total length of the grass. The average lawn should be approximately 1-1/2 to 2 inches long during cool months, and between 2 to 3-1/4 inches long during hot months.

WARNING Always remove the battery pack from the mower after finishing work.

Slope Gauge (Fig. 16)

WARNING
Do not mow a slope that has an angle of greater than 15° (a rise of approximately 2-1/2’ (0.75m) every 10’ (3m)). Mow across the face of a slope and never up and down.

Use Fig. 16 as a guide in order to identify slopes that cannot be mowed safely .

Mulching Tips

WARNING
Inspect the area where the mower is to be used and remove all stones, sticks, wire and other debris that might be thrown by the rotating blade.

• Release the switch to turn off the mower blade rotation when crossing any graveled areas; stones can be thrown by a rotating blade.
• Set the mower to the highest cutting height when mowing on uneven ground or in tall growth.
• For effective mulching, do not cut wet grass; it tends to stick to the underside of the deck, preventing the proper mulching of grass clippings. The best time to mow grass is in the late afternoon, when the grass is dry and the newly cut area will not be exposed to direct sunlight.
• For the best mulching performance, set the cutting height to remove approximately one third of the grass-blade length, ideally no more than 1-1/2’’ at one time. If the grass is overgrown, it may be necessary to increase the cut height to make it easier to mow and to prevent overloading the motor. Slow your cutting pace in tall or thick grass conditions. For mulching extremely thick or tall grass, it is advisable to first cut at a high cutting-height setting, and then re-cut to the final cut height. Otherwise, make narrower cuts and mow slowly. ALWAYS MAKE SURE THAT THE BLADE IS SHARP.

WARNING Always remove the battery pack from the mower after finishing work.

MAINTENANCE

WARNING To avoid serious personal injury, always remove the battery pack from the tool before cleaning or performing any maintenance.

WARNING
When servicing, use only identical replacement parts. Use of any other parts could create a hazard or cause product damage. Periodically inspect the entire product for damaged, missing, or loose parts such as screws, nuts, bolts, caps, etc. Tighten securely all fasteners and caps and do not operate this product until all missing or damaged parts are replaced.

5. While still wearing protective gloves, hold the blade with one hand and turn the fan with inner flange with the other hand to align the holes in the blade with the through holes in the inner flange (Fig. 21).
6. Place a metal rod (e.g., a 3.5’’ length screw bit) with diameter of 5/16’’ (8mm) into the fixing hole to act as a stabilizer (Fig. 22).
7. Use a 9/16’’ (14mm) torque wrench to tighten the bolt clockwise. The recommended torque for the blade bolt is 36~43 ft-lb (49-59Nm).

Sharpening the Blade

• WARNING Always protect your hands by wearing heavy gloves or wrapping the cutting edges with rags or other materials when performing any maintenance on the mower blade. Always remove the battery pack when servicing or transporting the mower.
• WARNING Use proper eye protection while removing, sharpening, and installing the blade.
• WARNING A worn, cracked, or damaged blade can break and pieces of the damaged blade can become dangerous projectiles. Thrown objects can cause serious injury. Inspect the blade regularly and do not operate the mower with a worn or damaged blade.
• NOTICE: Keep the blade sharp for best mower performance. A dull blade does not cut grass cleanly or mulch properly.

A dull blade can be sharpened, but a blade that is excessively worn, bent, cracked, or otherwise damaged must be replaced. A worn or damaged blade can break, causing blade pieces to be thrown from the mower.

If the blades are found to be bent, take the lawn mower to an authorized SKIL service center for inspection.

Sharping Frequency
Sharpening the blade twice during a mowing season is usually sufficient under normal circumstances. Sand causes the blade to dull quickly; if your lawn has sandy soil, more frequent sharpening may be required.

When Sharpening the Blade:

• Make sure that the blade remains balanced.
• Sharpen the blade at the original cutting angle.
• Sharpen the cutting edges on both ends of the blade, removing an equal amount of material from each end.

To Sharpen Blade in a Vise:

1. Remove the blade from the mower.
2. Secure the blade in a vise (Fig. 23).
3. Wear proper eye protection and gloves and be careful not to cut yourself.
4. Carefully file the cutting edges of the blade with a fine tooth file or sharpening stone, maintaining the original cutting edge angle.
5. To check the blade balance: clamp a nail or a screwdriver with a round shank in the horizontal position. Position the blade so that the nail or round shank of the screwdriver supports the blade through its center hole. Balance the blade horizontally. If either end of the blade rotates downward, remove some metal from the heavy or lower end until the blade is balanced. It is balanced when neither end drops (Fig. 24).
6. Replace the blade on the mower and tighten it securely.

WARNING
An unbalanced blade will cause excessive vibration when rotating at high speed. It may cause damage to the mower and could break, causing personal injury.

Replacing the Wheels

WARNING Always remove the battery pack when servicing or transporting the mower.

1. Turn the mower on its side with the upper surface against a wall.

2. Use a flat blade screwdriver to pry the dust cover away from the wheel.

3. Use an adjustable or 1/2 inch (13mm) wrench to turn the bolt counterclockwise to loosen it.
   For the front wheel (Fig. 25), and the rear wheel of the non-self-propel lawn mower (Fig. 26):

4. Remove the bolt, the worn wheel from the wheel axle.

5. Mount the new wheel on the wheel axle. Note that the round recess must face outward.

6. Lock the wheel with the bolt by tightening the bolt clockwise.

7. Mount the dust cover onto the wheel and press it in place.

For the rear wheel of the self-propel lawn mower (Fig. 27), remove the drive gear from the worn wheel and assemble it to the new wheel with the 3 screws.

Lubrication
Lubricate with light oil as directed below at least once each season.

• Periodically lubricate the locking pin in the handle adjustment knob (Fig. 28), the torsion spring and pivot of the rear-discharge door (Fig. 29) with light oil to prevent rust.
• Lubricate the wheel center hole (or the wheel axle) with light oil when the wheel seems impeded during operation.
• Place the mower into the locked storage position and remove the battery:

1. Move the cutting-height adjustment lever toward the front and engage it in the lowest setting.
2. Open the handle-locking clamps and fully recess the side rails to the compact position.
3. Turn the handle adjustment knob to release the handle.
4. Gently pivot the handle toward the front of the mower; turn the handle adjustment knob to lock the handle in the locked storage position. Make sure that the lock pin has engaged in the locked storage position.

Place the folded mower upright on the ground (Fig. 30 & 31).

1. Lubricate the deck-height adjustment joint.
2. For self-propel mower, lubricate the bearings on the drive shaft near the rear wheels (Fig. 31).

Replacing the Trailing Shield

WARNING
Always remove the battery pack when servicing or transporting the mower.

WARNING
Never operate the mower unless the trailing shield is in place and working. Never operate the mower with damaged safety devices. Failure to do so can result in personal injury.

The trailing shield is subject to wear and damage, which could expose moving parts or allow objects to be thrown. For safety protection, frequently check the trailing shield and replace it immediately with only the identical replacement part. Contact SKIL service center for support.

1. Remove the battery.
2. Turn the mower on its side with the upper surface against a wall.
3. Remove the three screws with a screwdriver, then remove the trailing shield (Fig. 32).
4. Replace with a new trailing shield.

Storing the Mower
The following steps should be taken in order to prepare the lawn mower for storage.

1. Remove the battery pack from the mower and store the battery pack at room temperature in a dry location.
2. Clean the mower as described earlier in the maintenance section.
3. Inspect the blade and replace it or sharpen it if required.
4. Lubricate the mower.
5. Store the mower in a dry, clean location. Do not store it next to corrosive materials, such as fertilizer or rock salt.
6. Store the mower in a covered, enclosed space, that is cool and dry and out of the reach of children.
7. Do not cover the lawn mower with a solid plastic sheet. Plastic coverings trap moisture around the mower, which causes rust and corrosion.

The handle assembly can be folded away completely for storage:

1. Remove the grass bag.
2. Move the cutting-height adjustment lever toward the front and engage it in the lowest setting.
3. Open the handle-locking clamps and fully recess the side rails to the compact position.
4. Gently pivot the handle toward the front of the mower; turn the handle adjustment knob to lock the handle in the locked storage position. Make sure that the lock pin has engaged in the locked storage position.
5. Store the mower upright or flat (Fig. 33a & 33b).

WARNING
If the mower to tips over from the upright position, mower damage or personal injury may result. Always keep the mower stable and out of the reach of children when it is in the upright position. If possible, lay it flat for storage.
