Check Hydraulic Oil Level - Hitachi ZW 550-6 Operator's Manual

Check Hydraulic Oil Level

--- every 10 hours (daily)
IMPORTANT: If the oil level is not viewed in the level
gauge, immediately refill hydraulic oil up to the
correct 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 7-6 for preparation of inspection/
maintenance work.
2. Check oil level with level gauge (1) on the hydraulic
oil tank. Float (2) must be seen on the gauge. If
necessary, add oil.

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