running or right after the engine is stopped. If the cap is
open the very hot steam will blow out, which causes
serious burns.
Wait until the coolant temperature goes down.
Slowly open the cap to release the pressure.
Always release inner pressure from hydraulic system
Pressurized oil may spout out if the hydraulic line is
disconnected without releasing the inner pressure of the
hydraulic system. Release the inner pressure before
disconnecting a hydraulic line.
Precautions for high pressure oil
It is very dangerous if the high pressure oil enters your
skin or eyes.
If oil enters your skin, immediately go to the doctor and
get medical attention.
Precautions for battery
When maintaining the electrical system or carrying out
welding, remove the lead connected to the negative
terminal (-) of the battery.
The battery can generate flammable gases and there is
the danger of the gases catching fire and exploding. Also,
dilute sulfuric acid is used for the battery liquid. Take
sufficient care while handling.
Prevent fire or explosions
Keep away fuel, lubricant and coolant from any fire or
heat. Most of them are very flammable.
Never place flammable materials or objects close to fire or
heat.

WORK INSTRUCTIONS
Digging
The digging force of the arm cylinder is maximized when the angle between the arm cylinder and arm is 90
degrees.
The digging force of the bucket cylinder is maximized when the angle between the bucket cylinder and the arm
link is the same as the angle between the arm link and
bucket link. Improve the digging work efficiency, making use of these
angles properly.
In digging, pull the arm to dig with the bucket. Raise and lower the boom to adjust the depth.
Ditching
Place the machine along the ditch direction and travel it backward with the progress of ditching.
Loading
After digging, raise the boom, swing and load soil onto the dump truck.
Gutter Digging
It is possible to dig gutters in narrow spaces by swinging the boom.

PRECAUTIONS FOR WORKS
Never stop swinging by hitting
Never stop swinging by hitting or pressing the bucket
against the wall of the ditch. Otherwise, strong impacts are applied to the machine and the service life is
shortened.
Never sweep with the bucket
Avoid sweeping the bucket like a broom in order to level off ahead of machine. This causes side strains and wear
on the boom, arm, and bucket.
Precautions for works at the cylinder stroke end
At the stroke end of the cylinder, the bucket moves faster. Thus, operate the bucket slowly with care not to allow soil
and sand to drop.
When the cylinder is moved to the stroke end, large forces are applied to the cylinder piston and the service
life is shortened. Give some margins to the cylinder in
works.
Hammering is prohibited
Never use the bucket instead of picks or for hammering or
piling. Otherwise, excessive forces are applied to the
machine, resulting in dangerous accidents.
Do not overload to cylinder
Do not forcefully conduct digging operation beyond the
capacity, which may overload any cylinder and open its
relief valves. This causes damage to the hydraulic system and machine.
OPERATION
45V4 • 55V4 • 60V4 ENG 2-37
Do not crawl with the bucket
Do not drag the bucket on the ground by crawling. Level
the ground with proper equipments in a correct way.
Bring both sides of the blade into contact with the
ground
Bring both sides of the blade into firm contact with the flat
ground when using the blade as a stabilizing plate in
digging work. If a single side of the blade contacts the ground, the blade
may be damaged.
Pay attention to the blade when digging deep ditches
The cylinder may hit against the blade. Thus, the boom cylinder may contact with the blade when digging a deep
ditch.
Be very careful in operation.
Works in damp grounds
Place mats or the like to protect the footing in advance
when carrying out works in damp grounds or muddy
places. Drive the machine with great care not to enter muddy
places.

Escape from a muddy place
If a single side enters a muddy place, lower the bucket
onto that muddy ground to lift the crawler, place logs, wood. under the crawler and escape from that place.
If both sides enter a muddy place and the machine cannot
be driven, place logs or wood under crawlers one by one in the same way as shown above, bite the front ground
with the bucket, pull the arm in the same way as digging
to move the machine, and escape from that place.
Works in water
x The allowable water depth is up to the center of the
upper roller or the top of the slide pad.
Check the water depth and ground before working in water or traveling the machine across the river. Do not
go into water deeper than the allowable water depth.
The machine may sink little by little if the ground is soft. Pay great attention to the footing in work.
If the bucket is dipped in water for long, grease the
pins around the bucket sufficiently until used grease oozes out.
x The engine may get wet with water and the radiator fan
may be broken if the machine climbs a steep slope when going out of water. Be very careful.
Countermeasures if the machine is buried up to the
super structure
If the machine is buried with water, soil or sand up to the
super structure by mistake the swing bearing may wear abnormally. It is necessary to change grease in the
turning structure or overhaul and repair the turning
structure immediately. Stop operation and ask greasing, overhaul or repair works from the nearest service office.

Adjust the Bucket Clearance
The standard bucket has a bucket clearance adjusting mechanism to prevent backlash.
1. Bring the back of the bucket into slight contact with
the ground, and swing the machine a little to the right to make the condition where the top of the arm is
pressed against the inside of the clearance adjusting
mechanism.
2. Stop the engine.
3. Move the O-ring to above the boss and measure the
clearance of the bucket and arm.
4. Remove the shim to adjust the clearance if the
clearance is 1 mm or more.
The thickness of the shim is 0.8 mm. Do not remove the shim if the clearance is 0.8 mm or less.
5. Remove the four bolts. Remove as much shims as
the amount of backlash (wear amount) from inside
the flange.
6. Attach the flange. Tighten the four bolts.
7. Measure the clearance.
The standard clearance is 0.1 to 1.3 mm.

CRAWLER TRACK
Rubber Track Maintenance
Rubber track should be repaired or exchanged if goes into any of the conditions described below.
If it is necessary to repair or replace it, contact your IHI
dealer.
Height of Lug
The rubber track can be used even if it is worn, however,
if it is excessively worn, the rubber track is likely to be
slippery and more travel force is required. If the remaining lug is less than 5 mm high, exchange it with
brand-new one.
Exposure of Steel Cord
If steel cord is exposed because of weary rubber or damage, exchange it with brand-new one.
Cutting of Steel Cord
Replace immediately if more than half of the steel cord
layer on one side has been cut. If this is left as it is, the rubber tracks breaks suddenly
during operation, thereby leading to a serious accident.
Crack of Covering Rubber
If a crack is 30 mm or more long and 8 mm or more deep, repair the covering rubber immediately. If steel cord
appears even if a crack is small, repair it immediately.
Otherwise, water may come into a crack, which rusts steel cords and cuts off the rubber track.
Dislocation of the iron core
Exchange the rubber track with a new one if one or more
iron cores are dislocated from it.

Inspection of Crawler Track
The machine needs to be raised to inspect the track tension. If the machine drops by mistake during inspection, a serious injury may result. Be very careful when the machine is raised.
The conditions of wear and sag of the crawler tracks differ with the conditions of the work sites. If the slack crawler
tracks are used, they may be slipped off. Inspect and
adjust their tension as the necessity requires.
Inspection
1. Raise the machine using the attachment and blade
until the crawler tracks become apart from the ground.
Support the crawler frame securely with blocks, etc.
2. Measure the clearance between the tread of the
lower roller near the center and the tread of the crawler track.
The tension is proper if the clearance is as shown
below.
10 to 20 mm (Rubber track)
30 to 50 mm (Steel track)
Raise the machine until the tracks are apart from the ground.
