MAINTENANCE
SERVICE PROCEDURE
EVERY 100 HOURS SERVICE
CHECK ALCOHOL LEVEL IN ALCOHOL INJECTOR, ADD ALCOHOL
(Machines equipped with alcohol injector)
During the cold season, check the ethyl alcohol level every 100
hours on the service meter.
When removing filler cap (1) of the alcohol injector to carry out the
inspection, loosen it slowly to release the remaining pressure
before removing it.
If the alcohol level is low, add alcohol to the bottom surface of the
threaded portion of the filler cap.
REMARK
On this machine, air is used to operate the brakes. When the machine is operated in cold weather, the moisture
in the air will freeze and cause problems such as defective operation of the valve, so add ethyl alcohol to the air
system to lower the freezing point.
When filling the alcohol injector with alcohol before the cold season, release the remaining pressure, remove the
cap, then add 1.4 liters (0.37 US gal) of ethyl alcohol through the filler port.
After the cold season, loosen drain valve (2) and drain the ethyl alcohol.
