Maintenance & Engine Operation - Minuteman Mirage M220028K17X Parts And Instruction Manual

MAINTENANCE OF THE ENGINE
The proper maintenance of your propane powered engine is vital to safe operation. LPG engines are dependent on
engine tune up, and air filter replacement. CO concentration (production) increases significantly when the air to
propane ratio becomes propane rich. Follow the recommended maintenance schedule for the engine found in the
engine operator/owner manual as well as the maintenance and adjustments schedule found in the engine
operator/owner manual that was supplied with the equipment.
OPERATION
PREPARING THE ENGINE FOR USE
NOTE: Before using any type of powered equipment, proper safety dictates you should visually inspect it. Check the
following:

ENGINE OIL LEVEL. To get an accurate reading, insert the dipstick but DO NOT screw in. Refer to Engine
Manual for further instruction.

BONNET FILTER - Make sure the bonnet air filter atop the engine is clean. It should be changed hourly and
thoroughly cleaned before reuse.

CYLINDER Fill the cylinder following the instructions (see "Refilling and Storing Propane Cylinders." section)

FUEL SYSTEM - Check for any sign of wear of the entire fuel system ie the Cylinder, fuel hoses, fittings and
etc., such as cracks or any corrosion. Replace hoses or correct any problems before operating the engine.

Screw the brass propane line fitting onto the cylinder 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 propane line fitting
is COMPLETELY seated into the service valve.
STARTING THE ENGINE
1. Propane powered engines are designed to be started in the IDLE throttle position. This creates the vacuum
necessary to open the lock-off valve inside the regulator. Actuation of the throttle lever will keep the lock-
off valve from opening and the engine from getting propane so the engine will not start.
2. Proper maintenance will insure easy starting.

4. Proper maintenance will insure easy starting.
5. Open (counterclockwise) the service valve on the propane cylinder about one and a half turns.
6. Engage starter for a MAXIMUM of 5 to 6 seconds or until the engine fires. Serious starter damage will
result if this is exceeded and the warranty may not apply.
7. 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 fails to start, see the Troubleshooting Guide.
STOPPING THE ENGINE
ONLY IN AN EMERGENCY should the key switch be used to stop the engine.
1. Close (clockwise) the service valve on the propane cylinder.
2. ALWAYS allow the engine to run until it stops from lack of propane.
3. Disconnect the propane line from the cylinder.
Turn the "kill switch" or Ignition Switch to the "off" position.
4.
5. When you are finished with the engine, store the propane cylinder outside the building, in a SECURE place
away from heat or direct sunlight.
