Brake System - NC SW6 Maintenance Instructions Manual

BRAKE SYSTEM

The brake system is filled with high grade hydraulic oil.
DO NOT USE CONVENTIONAL BRAKE FLUID.
This will cause serious damage to the dumper and degrades the brake performance to
dangerous levels. NC recommend Fuchs Renoil HVZ15
The brake system is filled via a fluid reservoir which is remotely mounted from the brake
master cylinder. The reservoir is located under the bonnet on the rear anti recirculation
baffle.
Normally, adjustment of the brakes is not required due to the automatic compensation which
is built into the axle brake design. But bleeding of the system may be necessary on occasions
if pipe work is damaged causing system leakage. A LED is provided on the display to
indicated if the brake fluid becomes low
The brakes on this dumper provide means of effective braking with
minimum maintenance. However it is vital during maintenance on the
dumper that the general condition of the system i.e. pipe work, pedal
operation, fluid level and general tightness is checked and deficiencies
corrected immediately. FAILURE TO DO SO COULD RESULT IN
SERIOUS INJURY OR DEATH.
BRAKE SYSTEM BLEEDING
Position the machine on firm level ground and ensure
•
the park brake is engaged and that one pair of wheels
is blocked on each side.
Ensure the skip is in the lowered position and locked
•
in the forward position.
Ensure the brake fluid reservoir is full and that during
•
bleeding its level does not fall below the ADD level
(B) mark.
Attach a tube to the brake bleed screw (C) ensuring
•
that the free end of the tube is immersed in fluid
contained in a suitable container.
Open the brake bleed screw and apply full brake
•
pedal strokes of the brake pedal until all air is
expelled.
Close the brake pedal screw with the pedal fully
•
depressed.
Repeat the procedure using the opposite bleed screw
•
Top up the reservoir to the MAX level (A) mark.
