bolt. Never exceed the
above lengths and never exceed 50
lbs-ft. of torque on the release nut
or the chamber may be damaged.
TRAILER BRAKES
Kalmar tractors are designed to use the
trailer’s brakes when towing trailers. All
Kalmar tractors are equipped with a trailer
Supply
air line and a trailer
Service
air
line. The service line is BLUE. The supply
line is RED.
When the vehicle is towing a trailer and
the service and supply line are connected
to the trailer, the trailer brakes become
part of the tractor’s brake system. The
tractor service brakes control the trailer
service brakes. The tractor parking brake
control operates the tractor and trailer
spring brakes. This is why it is critical that
the operator always connect both air lines
to the trailer.
TRAILER AIR LINES
The service air line (blue hose) operates
the trailer service brakes. The supply air
line (red hose) only supplies air to the
trailer spring brakes to release them. If
only the supply air line is attached to the
trailer, the trailer service brakes will not
operate. The tractor service brakes will be
doing all the braking for the combination
and braking distances will be dramati-
cally increased. Without the trailer service
brakes working, jack-knifing and loss of
vehicle control is much more likely during
heavy braking.
WARNING - Always
connect both trailer air
lines when towing a trailer.
Failure to connect both
the trailer service (BLUE), and the
trailer supply (RED) air lines greatly
reduces braking ability of the trac-
tor trailer combination and creates
a serious hazard. This increases the
possibility of an accident and could
result in serious injury of death.
ENGINE
Kalmar tractors come equipped with a
variety of engines. Kalmar provides the
engine manufacturer’s operation manual
with each vehicle. It is the operators re-
sponsibility to read the engine operation
manual and follow all instructions pro-
vided by the engine manufacturer.
Engine performance is very important
to the efficient operation of the Kalmar
tractor. Failure to properly maintain and
operate any engine can lead to very
costly repairs and extensive down
time.
KNOW YOUR ENGINE AND
MAINTAIN IT!
NOTE - This manual only contains basic
information on engine operation that apply
specifically to the Kalmar tractor, or is
applicable to all diesel engines.
If you did not receive an engine operation
manual, contact your Kalmar dealer.
CAUTION - Failure to read
and follow engine manufac-
turer’s instructions regarding
engine operation may lead
to severe engine damage. Read the
Engine Operation Manual before
operating this vehicle.
