Checking The Fluid Level In The Radiator; Checking The Braking System Oil Level - Komatsu WB93S-5 F50003 Operation & Maintenance Manual

MAINTENANCE PROCEDURES
4.8.6.b

CHECKING THE FLUID LEVEL IN THE RADIATOR

Carry out this check with the machine parked on level ground and loader arm lifted with engaged safety
q
lock.
Do not remove the radiator cap when the fluid is hot, since the fluid may be sprayed out of the radiator
q
and cause burns.
Loosen the cap slowly to release the pressure before removing it.
q
The radiator cap can be reached after opening the engine hood
(see "3.5.1 ENGINE HOOD").
Remove the cap (1) and make sure that the fluid level is very near
the filling hole.
IMPORTANTE
If the fluid level in the radiator is low and the expansion
q
tank is filled with coolant, check for tightness and make
sure that there are no air leakages from the pipe that
connects the radiator to the expansion tank.
If the problem persists, contact your Komatsu Dealer.
4.8.6.c

CHECKING THE BRAKING SYSTEM OIL LEVEL

This operation must be carried out when the warning light (1) on the front instrument panel comes on (see "3.3.1
pos. 8 - LOW OIL PRESSURE OR BRAKING SYSTEM FAILURE WARNING LIGHT").
The brake fluid reservoir (2) can be reached after removing the
front guard (3).
This is a visual check and, if necessary, the reservoir must be
topped up with the prescribed fluid until reaching the MAX. mark
(see "4.3 FUEL, COOLANT AND LUBRICANTS").
IMPORTANTE
Use new oil only.
q
If constant and considerable leakages are observed, it is
q
advisable to contact a Komatsu Dealer to have the system
checked and the necessary repairs carried out.
