Grounding Instructions

120 Volt Machines

This product must be grounded while in use to protect the operator from electrical shock. The machine is provided with a three-conductor cord and a three contact grounding attachment plug to the fi t the proper grounding type receptacle. The green (or green and yellow) conductor in the cord is the grounding wire. NEVER connect this wire to other than the grounding pin of the attachment plug. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electrical shock. This product is equipped with a cord having an equipment grounding conductor and grounding plug. The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

WARNING: Improper connection of the equipment grounding conductor can result in a risk of electric shock.

Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. DO NOT modify the plug provided with the product – if it will not fi t the outlet, have a proper outlet installed by a qualified electrician.

This product is for use on a nominal 120 volt circuit and has a grounding attachment plug that looks like the plug illustrated as (A) in the sketch. Make sure that the machine is connected to an outlet having the same confguration as the plug. No adapter should be used with this product.

WARNING: To prevent possible electric shock, protect the machine from rain. Keep the machine in a dry building.

WARNING: To prevent possible electric shock, always use a 3-wire electrical system connected to the electrical ground.

WARNING: DO NOT cut, remove or break the ground pin. If the outlet does not fi t the plug, consult your electrical contractor.

WARNING: Have worn, cut or damaged cords replaced by an authorized service person. Extension Cords

Use only an approved extension cord with three conductors, a plug with three terminals, and a connector body with three holes. The machine has a power cord with wire size 12 AWG (AWG means American Wire Gauge).

WARNING: If you use an extension cord, use an extension cord with minimum wire size 12 AWG. DO

NOT use an extension cord longer than 50 feet. DO NOT join two extension cords.

Machine Components

Operator Handle Grips
Use the operator handle grips to operate and move the machine. The switch levers on the underside of the handle grips, turn the motor on and off. Locate the handle grips in a comfortable operating position and lock the handle release lever in place. While operating the machine, slightly raising or lowering the operators handle will help the operator control the machine.

Switch Levers
The switch levers activate the switch module to turn the motor on and off. The switch module will not activate unless the switch lever safety lock is pressed first. To operate the machine, only one switch lever has to be engaged. This allows the operator to alternate hands while using the machine. To stop the motor from turning, release the switch levers.

Switch Lever Safety Lock
The switch lever safety lock is to prevent someone from accidentally turning the machine on. To turn the machine on, always make sure the handle is lowered in the operators position and the handle release lever is locked. Push and hold the switch lever safety lock with one hand, while engaging one of the switch levers. Once the machine has started, the switch lever safety lock can be released.

Water Tank
The water tank can be filled with clean water. This tank is for water only. DO NOT place any flammable, corrosive, and/or toxic liquids and powders in the water tank. Remove the fill cap to add water to the tank and replace the cap to prevent splashing of water on the electrical components during use. Always drain any remaining water from the tank before storage.

Handle Release Lever
This handle is used to release or lock the operators handle. Pulling up on the lever will allow the handle to move freely. Pushing down on the lever, horizontally, will lock the handle in place. The handle should always be locked while in use, as well as during transport or storage.

Cord Hook
To prevent the cord from being damaged while not is use, wrap the cord around the cord hook and the top of the operators handle.

Water Release Handle
Pulling up on this handle will open the valve inside the tank and allow water to flow from the water tank to the driver. Water will only flow from the tank while the handle is raised. To stop the flow of water from the tank, release the handle. The amount of flow can be varied by how far the handle is raised.

To drain the water tank, place the machine over a drain. Remove the fill cap and use the water release handle to drain the tank. Replace fill cap when finished.

Power Cord
Use only the supplied power cord with this machine. The power cord is sized to be used with this machine. To attach the power cord to the machine, insert plug on the back of handle into the female receptacle of the power cord. Properly align the plug pins with the holes of the receptacle, push together and twist to lock the cords in place.

How to Operate the Machine

Installing the Pad Driver

WARNING! Drain the water from the tank before tilting the machine back.

Place the handle in the upright (vertical) positions and lock the handle release lever. Tilt the machine back on the transport wheels and let the handle rest on the floor. Align the lugs with the corresponding slots in the pad driver and turn the pad driver counterclockwise to lock it in place. To remove pad driver, give it a quick hard turn clockwise.

CAUTION! Using the wrong pad, brush, or tooling on this machine can overload the motor.

Operation

1. Unwrap the power cord and plug it into the properly grounded outlet.

2. Pull up on the handle release lever (5). Move the operator handle (7) downward until your arms are almost straight. Push down on the handle release lever (5) to lock it in place.

3. Lift up on the operator handle (7) until the driver if flat against the floor.
   DANGER!: Machine can have high starting torque. Do not operate machine on rough or uneven surfaces. Do not operate on a slope. It is possible for the machine to move suddenly from side to side and even leave the ground if misused during operation. Only experienced operators should use machine for applications that impart high torque on the machine. If unable to control the machine during operation, release the handle and step away from the machine. It will stop automatically.
   WARNING! Be prepared to control the machine as soon as the motor starts. Just a slight up or down movement of the operators handle (7) will make the machine move from side to side. Raise the handle to go right. Lower the handle to go left.
   CAUTION! Immediately start moving the machine back and forth. Keep the machine moving while the motor is running to avoid damage to the floor.

4. Hold one of the operator handle grips (1) firmly, push the switch lever safety lock (2) and the compress the switch lever (3) to start the motor.
   Note: When the switch levers (3) are released, the machine shuts off immediately.

5. To release water from the water tank, pull up on the water release handle (4). The water will stop flowing once the handle is released.

6. To change the motor speed, use the motor speed switch (8) on the front of the operators handle (7).
   

Note: Inexperienced users should practice operating the machine prior to beginning their project. Practice in a large open area where the floor is smooth, with only a cleaning pad on the machine. The user should practice operating in this manner until they can control the machine consistently

After Use

1. Place the operators handle (7) in the upright (vertical) position and unplug the power cord. Wrap the power cord around the operator hand grips (1) and the cord hook (6).
2. Tilt the machine back and remove the pad driver from the machine. NEVER store the machine with the pad driver on the machine.
3. If there is any water in the water tank, place the machine over a drain. Using the water release handle (8), drain the water tank.
4. Wipe the entire machine with a clean, damp cloth.
5. Inspect the entire machine and all accessories for damage. Perform any required maintenance or repairs before storage.
6. Store the machine in a clean, dry place with the operator handle (7) locked in the upright position.
