--- every 10 hours
IMPORTANT: If the oil level is not viewed in the level
gauge, immediately refill hydraulic oil up to the
appropriate level. Failure to do so may result in a
serious failure in the hydraulic system.
If the oil level is higher than the level gauge, drain oil
down to the appropriate level using a pump.
1. Park the machine following the same procedures as
described on page 7-7 for preparation of inspection/
maintenance work.
2. Check oil level with level gauge (1) on hydraulic oil tank.
The oil must be between the marks on the gauge. If
necessary, add oil.

NOTE: During the cold weather season, check the oil
level after warming up the hydraulic oil by referring to the
instructions described in the "Warm up operation" group.
