27EXCAVATOR OPERATION
C Locking the service port pedal
The service port pedal can be locked downward
in order to use an attachment such as hand
breaker and hand auger. Please make a hole to
pass the bolt through the floor mat with a knife
etc. when you lock the service port pedal. The
bolt which fixes the pedal is in the tool kit.
Please tighten the bolt until you are able to
depress the service port pedal.
A When the service port is not being used, be
careful not to lock the pedal.
Because the hydraulic oil temperature will
rise abnormally, causing problems with the
hydraulic components.
IMPORTANT INFORMATION ON
EXCAVATOR OPERATION
To avoid personal injury:
A After work, clean the machine and
lubricate all movable parts.
A Check oil level.
A Do not try to crush concrete or boulders
using side swings with the bucket. Also
avoid using side sweeps of the bucket to
move earth piles.
A Under all circumstances avoid the following
operations:
A Excavation using the gravitational impact
of the machine.
A Compacting of gravel or soil using the
dropping action of the bucket.
A Excavation using the travelling power of
the machine.
A Do not try to drop or shake of soil adhering
to the bucket in the manner shown in the
explanation below. This can cause damage
to the machine.
Adhering soil can be shaken off when the
bucket is being emptied by moving the
bucket out to the maximum stroke of the
cylinder. Should this not suffice, swing out
the arm as far as possible and operate the
bucket back and forth.
A Do not hit the dozer with the boom cylinder!
Make sure that the boom cylinder does not
hit the dozer when carrying out deep
excavation. If necessary swivel the upper
structure so that the dozer is at the back of
the machine.
A Pay attention when pulling in the bucket!
When pulling in the bucket (for driving or
transportation) avoid hitting the dozer.
A Avoid collisions!
When moving the excavator, pay attention
so that the dozer does not collide with
obstructions such as boulders etc..
Such collisions substantially shorten the life
span of the dozer and the cylinder.
A Support the machine correctly!
When stabilizing the machine with the dozer,
Iower the whole dozer fully on to the ground.
A If the water or mud level reaches higher than
the top of the tracks, the swivel bearing,
swivel motor gear and ring gear may be
exposed to mud, water and other foreign
objects.
The excavator must be properly pressure
washed after each use.
A Thoroughly clean the area around the
swivel bearing, swivel motor gear and
ring gear to remove foreign objects.
A Inspect the swivel motor oil sump (if
equipped) for water contamination. If
water is present, refer to operator's
manual for lubricant replacement
procedure.
A Refer to operator's manual for proper
swivel bearing, swivel motor gear and
ring gear lubrication procedures.
A Reinstall any protective covering if
removed earlier.
