TRANSPORTATION
When transporting a propane powered floor machine with the fuel cylinder attached, the cylinder should be securely fastened with service valve closed and coupling not attached. The machine should be secured to the vehicle to avoid movement. Tanks separate from the machine should be secured to avoid movement. NEVER STORE MACHINES WITH TANKS IN AN ENCLOSED VAN OR TRAILER. ALWAYS CHECK TANKS FOR OVERFILL BEFORE TRANSPORTATION.
STARTING AND OPERATION PROCEDURE
CAUTION: NEVER ALLOW MACHINE TO RUN FOR MORE THAN 10 SECONDS IN ONE SPOT OR DAMAGE WILL OCCUR TO THE FLOOR!
1. Check oil and fuel levels. Make sure oil and propane tank is not overfilled.
2. Check and clean recoil dust filter and carburetor filter. Make sure air filter is free of dust and debris. Never run buffer for more than 1 hour without cleaning air filter. Change filters when necessary.
3. Check pad and pad assembly, to make sure pad is centered and clean, and look for any problems with pad driver. To do this turn machine over on its right side.
4. Check belt tension, again turn machine over on its right side and squeeze belt together. Belt should depress between 1/4 and 1/2 inch. To change see maintenance instructions. (Page 13)
5. Open propane service valve, turn counter-clockwise to open.
6. Tilt machine backward with pad off the floor, move bail to IDLE position. Never start machine with pad on the floor.
7. With 115V starting system, plug in adapter to wall outlet and the starter box. Turn key to the on position and push button on start box. If machine fails to start allow approximately 30 seconds between tries, never engage starter more than 10 seconds at a time.
a. Never start buffer with pad on the floor, this will
cause the starter to burn out prematurely!
b. Never use starting fluids or any other forms of
flammable substance to assist the engine in starting!
8. Allow engine to warm up and run at normal operating speed before engaging pad with floor. Make sure pad is off the floor before engaging the clutch. Once machine is at normal operating speed and clutch is engaged, start walking and slowly lower the machine to the floor and begin burnishing the floor.
9. Machines with mechanical clutches: NOTE: Never engage clutch with pad on floor. Once machine has reached normal operating speed clutch is engaged automatically at 2400 engine RPM and start burnishing. Start burnishing when pad has reached top speed.
10. Always burnish on the right hand, so exhaust fumes are blown to the inside of the aisle. Be careful exhaust fumes and muffler are extremely hot and will damage merchandise. NOTE: Do not expose skin to muffler or
manifold - extreme heat, will burn.
11. For normal stops of the machine, turn propane service valve clockwise, to starve the engine of its fuel. Do not stop machine by using the bail or ignition key, you can trap fuel in the lines, which can cause a backfire and cause damage to the engine. NOTE: In case of emergency
always turn ignition key off. NOTE: Machines without clutch, the pad starts to rotate immediately when engine starts. Pad stops rotating when engine is off! No clutch!

OPERATION INFORMATION
ENGINE BREAK-IN
Engine break-in as a result of proper care during the first hours of operation of a new or rebuilt engine results in the ideal fitting of all internal moving metal parts, which is essential for top engine performance. For controlled engine break-in.
1. Operate the equipment as it is intended to be operated. However, for the first 3 hours, if possible, operate the equipment at about half the available engine power, occasionally operating at full engine power for brief periods. Also, if possible, avoid prolonged low-speed, low-power operation during engine break-in.
2. Proper engine oil is especially critical during break-in because of the higher engine temperatures that can be expected. See RECOMMENDED ENGINE OIL. Change the oil if it is not appropriate for the ambient temperatures during the break-in periods. See Table 1, Figure 1 Page 6.
3. Check the oil level twice a day or after every 4 hours of operation during the first 24 hours of operation.
4. Change the oil and oil filter after the first 5 hours of operation.
OPERATION IN DUSTY CONDITIONS
1. Keep the engine cooling fins and flywheel air inlet screen and precleaner (filter) clean.
2. Perform air cleaner maintenance more often than normal - as required.
3. Change the engine oil more often than normal. See Table 2, Page 10.
OPERATION IN HOT WEATHER
Pay particular attention to the following items when operating the engine in temperatures above 100°F (38°C):
1. Keep the engine cooling fins and flywheel air inlet screen and precleaner (filter) clean: See to it that nothing obstructs air flow to and from the engine.
2. Check the oil level more frequently.
3. Change the oil more often than normal. See Table 2, Page 10.
4. Make sure the engine oil viscosity is appropriate for the ambient temperature and change the oil if necessary. See Table 1, Figure 1 page 6.
OPERATION IN COLD WEATHER
Pay particular attention to the following items when operating the engine in temperatures below freezing.
After engine has reached operating temperature while pad is still off the floor. Before lowering burnishing head, adjust throttle to operating speed. After slowly lowering machine to floor, place hands lightly on the handle and allow the machine to create the floor pressure. Bearing down and pushing hard will lead to premature belt problems and operator fatigue. For smoother turns and greater maneuverability, buff aisles from the right side first. CAUTION: DO NOT RUN MACHINE FOR MORE THAN 15 SECONDS IN ONE SPOT OR BURNING WILL OCCUR.
IDLING AND STOPPING THE MACHINE
If for any reason the machine needs to be idled for short periods, simply tilt machine back on its rear caster and release throttle bail into Idle Position. Machine will now idle safely. (CAUTION: DO NOT IDLE BUFFER ON REAR
CASTER FOR MORE THAN TWO MINUTES. This will raise the emissions level.)
To stop machine tilt back on rear caster, turn valve on
propane tank off, and allow fuel in the lines to be used up. FOR EMERGENCY SHUT OFF ONLY: turn off ignition switch. Electric start models: use emergency stop switch on right side of control panel.
STORAGE
Only authorized and properly trained personnel should have access to propane tanks and machine. Making sure tank valve is closed, remove tank from buffer. Local Fire Codes may require storing tank in separate location. We recommend this, as well as following
Local Fire Codes.
Store machine and tank away from objects that may fall and damage them. Never store tank or buffer near open flame or heat producing devices. Make sure machine is cleaned properly prior to storage. To prevent damage pad holder, the pad SHOULD remain on machine during storage.
EMERGENCY STOP
Turn ignition key to OFF position. Units with emission control device and clutch. Release bail on handle to activate kill switch.
Make sure the engine oil viscosity is appropriate for the ambient temperatures and change the oil if necessary. See Table 1. If the temperature drops before you have the chance to change the oil, warm up the engine by moving the equipment into a heated space before attempting to start the engine or change oil.

REGULATOR OPERATION
LP-gas vapor enters at point (A), then passes into primary area (B) at point (28), where pressure is reduced from up to 250 p.s.i. at the tank to 4 p.s.i. in area (B). Fuel pressure against diaphragm (4) overcomes spring (6) and as movement increases, spring (9) will close lever (10). The primary diaphragm breather (not shown in drawing), is vented to secondary chamber so that rupture of this diaphragm would direct fuel into the carburetor. Fuel now moves through passage (E), past secondary valve (29) into secondary area (C). As negative pressure (vacuum) is created at carburetor venturi and is transmitted through dry-gas hose to chamber (C) atmospheric pressure, exerted through vent hole (G), forces down secondary diaphragm (18), secondary lever (24) and spring (22). Fuel will flow in proportion to air velocity through carburetor venturi, insuring an ideal mixture at all engine speeds. Whenever engine is operating, vacuum diaphragm (16) is down against floor (H) and spring (17) is collapsed. The idle and starting adjustment is made with tapered screw (27) which regulates the whisker wire system (not shown), opening up secondary orifice slightly (but only when vacuum diaphragm is drawn down). Very little vacuum is needed to start this vacuum diaphragm travel; 0.2” Mercury to start and 0.5” Mercury for full travel. The instant engine stops rotating, loss of vacuum in section (D) releases diaphragm (16), causing bumper (K) to push against secondary lever (24), overcoming action of whisker wire and insuring 100% lockoff. This patented Beam design will lock off primary pressures up to five times in excess of normal, permits starting without priming or choking.
