3 Description and Operation

6. Turn the caging tool 1/4 turn to engage with the slot on the
pressure plate.
7. Try to pull the caging tool out; it should not pull out. If it
does, repeat steps 5 and 6.
8. Thread the nut and washer down onto the threaded end of
the caging tool all the way to the canister.
9. Tighten the nut until the threaded portion of the release tool
is out. It should extend approximately 3 inches (76.2 mm)
out of the nut.
3 inches (76.2 mm) — Type 2430 and 3030 Chambers
4 inches (101.6 mm) — Type 3036 and 3636 Chambers
NOTICE
Never use an impact wrench to tighten the nut onto the
release bolt. Never exceed the above lengths and never
exceed 50 ft. lbs. (67.79 N•m) 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 trailer
Service
air line. The service line is
BLUE. The supply line is RED.
When the vehicle is towing a trailer and service and supply
lines 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 dramatically
increased. Without the trailer service brakes working, jack-
knifing and loss of vehicle control is much more likely during
heavy braking.
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 tractor trailer combination and creates a
serious hazard. This increases the possibility of an
accident and could result in serious injury or death.
