REQUIRED OPERATOR TRAINING

Original purchaser of this unit was instructed by the seller on safe and proper operation. If unit is to be used by someone other than original purchaser; loaned, rented or sold, ALWAYS provide this manual and any needed safety training before operation.

PREPARATION

• Before starting any removal of parts, proper preparation is very important for efficient work. A clean work area at the start of each job will allow you to perform service repairs easily and quickly.
• To reduce the incidence of misplaced tools or parts, place removed components with all attaching hardware in the disassembly order on a clean work surface.
• Organization is a key part of proper reassembly.
• Tools, instruments, and parts needed for the job should be gathered before work is started. Interrupting a job to locate tools or parts is a needless delay.

CAUTION : Remove enough fuel so that no spillage will occur. Remove battery to prevent spillage of electrolyte

CLEANING AND STORAGE

WARNING : AVOID SHARP EDGES which can cut. Movement of parts can cut off fingers or a hand. Wear gloves, and use extreme caution when servicing
IMPORTANT : Never spray unit with water or store unit outdoors to help prevent sealed bearing rust or corrosion. Water can seep into sealed bearings and reduce component life. Bearings are sealed against dirt and debris only.
A unit that is excessively dirty should be cleaned before work starts. Cleaning will occasionally uncover trouble sources. Dirt and abrasive dust reduce the efficient work life of parts and can lead to costly replacement.

When taking unit out of extended storage:

1. Check for any damage or loose parts. Repair, replace, or tighten hardware before operation.
2. If a preservative fluid was used in fuel tank, drain and discard. Fill fuel tank with fresh new fuel

SERVICE POSITIONS

Place unit on a flat level surface. ALWAYS stop engine. Assure unit is secure and will not tip over. Strap and clamp onto bench if needed.
A handlebar service position is provided for tipping the unit for cleaning and service (Figure 3). See Adjustments.

WARNING : ACCIDENTAL ENGINE START-UP can cause death or serious injury. ALWAYS stop the engine, remove key, wait for moving parts to stop and remove wire from spark plug before adjusting or servicing.
CAUTION : FUEL SPILLS may result in minor or moderate injury and/or damage to the unit. Before the unit is tipped up onto the housing, remove enough fuel so that no spillage will occur. Remove battery to prevent spillage of electrolyte.

IMPORTANT : When tipping to service engine or unit, use the following service positions for the brand and type of engine on your mower:

• Tecumseh & Robin Engines: Place the handlebar into the service position and tip the machine to the rear.
• Briggs & Stratton Intek Engines: Place the handlebar into the handlebar service position and tip the machine to the left, opposite the discharge opening.

Kawasaki : Place the handlebar in service position and tip unit to right.
IMPORTANT : If engine becomes “flooded” due to tipping, clean air cleaner and remove spark plug, put one teaspoon of oil in cylinder, turn engine over a few times and reinstall spark plug.

FILLING THE FUEL TANK

WARNING : EXPLOSIVE VAPORS and its FLAMMABLE FUEL can result in death or serious injury. Handle fuel with care.

• ALWAYS use an approved fuel container.
• No Smoking! No lighted Materials!
• No Open Flame!
• Allow engine to cool before maintenance. Gasoline is highly flammable and must be handled with care. Allow engine to cool several minutes before removing fuel tank cap. Never fill tank when engine is running or is hot from operation. DO NOT allow open flame, matches, or smoking in area. DO NOT overfill. Allow about 1/4″ of tank space for fuel expansion. Wipe up any spills and allow vapors to dissipate before starting engine. Use approved gasoline container.

To add fuel to fuel tank:

1. Put unit in open or well-ventilated area.

2. Stop engine and allow to cool.

3. Clean fuel cap and surrounding area to prevent dust, dirt and debris from entering fuel tank.

4. Remove cap.
   IMPORTANT : DO NOT use gasohol or gasoline containing alcohol because alcohol will cause internal parts to deteriorate. See Engine Manual for correct type and grade of fuel.

5. Fill fuel tank. (See Specifications for tank capacity.)

6. Replace fuel cap and tighten.

7. ALWAYS clean up any spilled fuel.

GENERAL LUBRICATION
Swivel Lubrication (swivel units)
See Figure 4.

• Apply Sten Mix Hi-Temp Grease or equivalent to the lube fittings. Order P/N: 00036800 – 3 pack of 3 oz. cartridges.
• When using Sten Mix Grease for the first time, all components should be thoroughly cleaned prior to lubricating.

Commercial Models
Grease fittings on rear axle housing every 25 hours.

CHECK MOWER BLADE
See Figures 5 and 6.

Regularly check mower blades for wear and that lock washer is fully compressed by cap screw (requires 25-30 ft-lbs (33-40 Nm) of torque on cap screw).

When blade needs sharpening:

1. Block blade to prevent rotation.
2. Remove cap screw, lock washer and blade from shaft.
3. Sharpen both ends of blade at original angle (25o), removing equal amounts of material from each end to maintain proper blade balance. New blades are balanced to within 1.3 in. oz. at factory. DO NOT grind around corner at tip of blade. If cutting edge of blade cannot be sharpened in
4. straight line to within 1/8 of an inch of its end, replace blade with Ariens replacement blade only.
5. Install blade, lock washer and tighten cap screw 25- 30 ft-lbs (33-40 Nm) until lock washer is fully compressed.

IMPORTANT : If mower is used under sandy soil conditions, replace blades when air lifts become eroded.

CHECK DRIVE BELT

Check drive belt for wear or damage. Replace belt if worn or damaged.

CHECK ENGINE/BLADE CONTROL

The engine/blade control must stop the engine and blade within 3 seconds after the bail is released. If the engine or blade continues to run, adjust or repair control immediately.
Engine control must stop engine ignition, at 3/4″ to 1-1/4″ from handlebar as control is released.

1. Start engine and slowly release control until engine stops firing.
2. Measure distance between handlebar and control at the point that engine stopped firing.
3. Turn cable nuts at handlebar mount clockwise if measurement is more than 1-1/4″ or counter-clockwise if measurement is less than 3/4″.
4. Turn nuts against mount to lock in position.

There must not be slack in cable.

To check, rotate blade in it’s cutting direction (this draws control rod fully in).
To eliminate slack in cable, turn nuts on cable at handlebar clockwise.

CHECK GRASS BAG
Check bag for wear or damage. Keep bag clean and dry. Replace only with Ariens original equipment replacement bag.

CHECK DRIVE CONTROL
Check operation of drive control. The drive must disengage completely when the bail handle is released. Adjust bail travel if necessary. See Figure 10.
When the wheel drive control is squeezed toward the handlebar, the extension spring, located at the bottom end of the traction cable, must start to extend when the control is between 1-1/2″ and 2″ (3.8 and 5 cm) away from the handlebar. To check:

1. Squeeze the wheel drive control toward the handlebar until the spring starts to open.
2. Measure the distance between the wheel drive control and handlebar at the handlebar indentation.
3. To obtain the proper adjustment, turn the cable nuts. Turn clockwise if the measurement is more than 2″; counterclockwise if the measurement is less than 1-1/2″. Tighten the nuts against the bracket to lock in position. If there is not enough thread length for adjustment, the opposite end of the cable can be adjusted.

Three Speed Drive Control
When the wheel drive control bail is squeezed toward the handlebar, the extension spring must start to extend when the control bail is between 3-7/8″ to 4-1/8″ away from the handlebar. The extension spring is located at the bottom end of the traction control cable.

To check the control cable spring:

1. Squeeze the wheel drive control bail towards the handlebar until the spring starts to open.
2. Measure the distance between the wheel drive bail to the handlebar indentation.
3. To obtain the proper adjustments turn the control cable nuts at the handlebar or the bottom of the control cable anchor against the anchor supports.

HANDLEBAR ADJUSTMENT
Holes in handlebar braces provide four height positions, a service position, and a storage position (except on professional models).

Use one of the four holes to adjust handlebar height to a safe, comfortable position. Place bolt on handlebar bracket through one of holes 1, 2, 3 or 4 in order of increasing height (See Figure 11).
NOTE : On Professional models nuts and bolts replace pins.
For storage, rotate handlebar forward and place pins through holes further up braces.

SPEED CONTROL BELL CRANK

The speed control bell crank holds the speed selector rod in position after a speed has been set. The spring washers may become loose with normal wear. If the speed selector rod does not stay firmly in position, adjust the speed control bell crank. See Figure 12.
To adjust:

1. Remove cover, fully compress the helical spring lockwashers with lock nut and then back lock nut off, one half turn.
2. If the speed selector rod is still too loose, tighten lock nut by small increments until it holds its position. Tightening the lock nut too much will not allow the speed selector rod to move at all.
3. Align notch in left hand side of cover with bolt and secure with knob

FRICTION WHEEL ADJUSTMENT

Early Models (Side Pull)
Adjust rear cutting height levers to middle position. Check to be sure there is slack in the friction wheel drive cable, if not readjust cable nuts.
Set speed selector at slowest speed and loosen the two cap screws on drive mount. Hold lever securing drive cable down toward mower pan and adjust drive assembly to bring friction wheel to within 1/16″ above drive disk. Tighten cap screws. Check for proper function of friction wheel and speed selector. Adjust cable nuts to remove slack.
