Machine Preparation
FILLING THE LP CYLINDER
This machine uses the 20 lb (9.1 kg) capacity cylinder, which meets the D.O.T. 4E240 standards.
These cylinders are also listed by UL. In addition, the steel cylinder meets European TPED
specifications and is CE compliant. Filling should be done ONLY by a qualified propane dealer.
A properly filled cylinder should not exceed 80% of the rated capacity. Do not overfill the cylinder
or use a liquid withdraw cylinder on the machine. The use of a liquid withdraw cylinder on a
vapor withdraw system could freeze the regulator and create a fire hazard.
INSTALLING THE LP CYLINDER
Place the cylinder on the cylinder platform at the back of the machine. Connect the fuel hose
coupling to the service valve by turning to the right (clockwise). HAND TIGHTEN ONLY! Make
sure coupling is not cross-threaded and check for leakage by noting any propane odors imme-
diately after cylinder is connected. Finally, secure the tank to the machine using the adjustable
strap. Remove slack by pulling on the loose end and securing with the velcro.
REMOVING THE LP CYLINDER
Reverse the above procedure. Always connect or change cylinders in a well-ventilated area.
ROK-BAK POSITION
1. Close the valve on the propane cylinder; allow the engine to stop.
2. Turn the machine OFF.
3. Remove the propane cylinder
4. Raise the handle to the full-up position (about a 45° angle).
5. Lift up on the front of the deck, rocking the machine back until it rests on the handle grips
(Figure 3).
6. When lowering the machine down, do not drop it. Slowly lower the machine to the floor until
the wheels are on the ground.
CHANGING THE PADS
1. Place the machine in the Rok-Bak position.
2. Remove centering device and inspect pad. If pad has worn to less than 1/4” (6mm), re-
place it.
3. If the pad holder has cracks or is damaged, replace as well. A damaged pad holder rotating
at high speeds may be an extreme hazard if it should come apart.
HANDLE ADJUSTMENT
The height of the handle can be adjusted by raising or lowering the handle. Loosen the handle
adjustment lever on the side of the handle. Move handle to the desired height and tighten the
lever.
