Safety precautions
• This propane fueled machine is intended for commercial use only. It is designed for oor maintenance.
Do not use the machine other than describe in this Operator’s Manual.
• All operators must read, understand and practice the safety precautions in this section as well as the
“Safety Awareness Manual” included in this manual.
• Only trained and authorized operators should operate propane powered oor machines.
• Check fuel cylinders for overll before taking them into the building or your van. (see Relling
Propane Fuel Cylinders).
Before Operating the Machine
• Check oil level.
• Check carburetor air lter.
• Check pad and pad holder.
• Adjust handle height.
• Install fuel cylinder in a well ventilated area.
While Operating the Machine
Even though the 89 db sound level is below OSHA’s PEL, it is the course of wisdom to wear hearing
protection while operating any internal combustion engine in an enclosed area.
If you smell the odor of propane, stop the engine, remove the cylinder and take it outside for
inspection.
Be aware of odors other than propane. Toxic emissions are produced by internal combustion engines.
Properly maintained engines produce a small amount of these gasses including carbon monoxide. Although
carbon monoxide has no odor, the hydrocarbons do and an elevation of odor may indicate increased CO as
well.
Do not allow the machine to run unattended except for short times while moving and obstruction.
Exhaust parts are extremely HOT. Be careful not to allow them to come into contact with anything or
anyone.
Do not attempt to change pads while the engine is running.
Machine Storage
• Stop the engine by closing the service valve on the fuel cylinder.
• Remove the key from the switch, if applicable.
• Remove the fuel cylinder from the machine and store it outside in a secure approved cabinet (see
“Propane Fuel Cylinders”).
• Clean and inspect air and dust lters.
