To avoid personal injury:
First lower all attachments

IMPORTANT:
Before fi lling oil, wipe away all sand and
dust from around the oil port. Make sure
you use an identical type of hydraulic
fl uid.
The excavator has been fi lled with
hydraulic fl uid before delivery. See
"RECOMMENDED OILS". (Do not mix
different oils!)
1. Park the excavator on a fi rm, fl at and
level surface.
Adjust the swing angle to the center.
Pull in the arm completely.
Pull in the bucket completely.
Lower the attachments and dozer blade
to the ground and stop the engine.
Track width increases [16 in. (1240

2. Check the oil level as to whether it lies
on the center of the gauge at normal
temperature (10 to 30ºC).
3. Enough oil is present if the oil level lies
between the markings.
4. Should the oil level be too low, fi ll oil
through the oil port before starting the
engine. This step is important for the
protection of the hydraulic system.
