MAINTENANCE.
CHECK LEVEL OF BATTERY ELECTROLYTE
To avoid gas explosions, do not bring fire or sparks near
G
the battery.
Battery electrolyte is dangerous. If it gets in your eyes or
G
on your skin, wash it off with large amounts of water, and
consult a doctor.
Carry out this check before operating the machine.
1. Open the battery door on the left side of the machine.
2. Remove cap (1), and check that the electrolyte is at the spec-
ified level (10 to 12 mm above the plate). If the electrolyte
level is low, add distilled water to the specified level.
If the battery electrolyte is spilled, have dilute sulphuric acid
added.
3. Clean the air hole in the battery cap, then tighten the cap
securely.
When adding distilled water in cold weather, add it before starting
operations in the morning to prevent the electrolyte from freezing.
LUBRICATE SWING CIRCLE (2 points)
1. Lower the work equipment to the ground.
2. Using a grease pump, pump in grease through the grease fit-
tings shown by arrows.
3. After greasing, wipe off all the old grease that was pushed
out.
BELTS, GENERAL
Before working on the engine or electrical system, disonnect
the negative (ground) battery cable. Tag the cable and con-
trols to warn against starting.
Replace badly worn, greasy or severely cracked belts immedi-
ately. These conditions prevent the belt from functioning correctly.
Prior to installing new belts, make sure all pulley grooves are
clean and not worn. If a pulley is damaged or if the grooves are
worn, it should be replaced.
