HOW TO OPERATE THE MACHINE

Preparing The Machine For Use
BEFORE using any type of powered equipment, proper safety dictates you should visually inspect it.
1. Adjust the HANDLE to a comfortable height and tighten the bolts to 30-50- ft/lbs.
2. BONNET FILTER - Make sure the bonnet air fi lter atop the engine is clean. It should be changed hourly and thoroughly cleaned before
reuse.
3. Oil Level -
(a) Check the engine OIL LEVEL.
(b) With the buffer sitting in a level position, unscrew the yellow oil fi ller cap, pull out, and wipe dipstick off with a clean cloth.
(c) Insert the dipstick into the tube, but DO NOT screw it back in.
(d) Pull the dipstick out and check the oil level making sure the oil level is in the operating range (grid area) shown on the dipstick. If the oil
level is in the "ADD" range, add enough engine oil to bring the oil level to the operating range. NOTE: NEVER overfi ll the engine oil as this
can lead to irreparable damage to the engine.
4. Fill the tank following the instructions as given under the previous heading: "Refi lling And Storing Propane Tanks." In addition, if your buffer
came with an "80% Safety Fill Tank" then it should ONLY be fi lled through the threaded valve with the larger diameter that is covered by a
yellow cap to ensure a "Full" level that is safe.
5. PAD AND PAD HOLDER - Inspect the condition of the pad and pad holder. Is there a pad? Is it properly attached? What is its condition?
Ensure the pad is clean and has at least a thickness of 1/3 inch. ALWAYS turn off the engine to clean or replace pad.
6. TANK and FUEL LINES - The tank has already been covered but do the fuel lines show any sign of wear and tear, such as cracks or any
corrosion? Screw the brass fuel line fi tting onto the tank service valve hand tight only. This connection MUST be secure because the service
valve has a safety valve inside it which will only open if the brass fuel line fi tting is COMPLETELY seated into the service valve.
Starting the Engine
1. The engine is designed to be started with the throttle in the idle position. This creates a vacuum necessary to open the lock-off valve inside
the regulator. Movement of the throttle lever will keep the lock-off valve from opening and the engine from getting fuel so the engine will not
start. Proper maintenance will insure easy starting.
2. Open (counterclockwise) the service valve on the propane tank about one and a half turns.
3. Ensure the buffer is tilted back so that the pad is off the fl oor
on all machines without a clutch.
4. Engage starter for a MAXIMUM of 5 to 6 seconds or until the engine fi res. Serious starter damage will result if this is exceeded and the
warranty may not apply.
5. Operate the engine at half throttle for approximately two minutes for proper warm-up. Then advance to full throttle for best results.
NOTE: If the engine refuses to start, see the Trouble Shooting Guide.
Stopping The Engine
1. Close (clockwise) the service valve on the propane tank.
2. ALWAYS allow the engine to run until it stops from lack of fuel and then turn off the key switch. ** ONLY IN AN EMERGENCY should the "kill
switch" be used.
3. Disconnect the fuel line from the tank.
4. REMEMBER, when you are fi nished with the machine, store the propane tank outside the building, in a safe place away from heat or direct
sunlight.
