3 Description and Operation
Failure to observe the following rules when parking the
vehicle may lead to death or serious injury.
1. Always apply the parking brake.
2. Never park the vehicle by leaving it in gear. Always
place the transmission shifter selector in the "Neutral"
position.
3. Never park a tractor trailer combination unless the
trailer parking brakes are operational and applied.
NOTICE
If the vehicle is parked in gear, the vehicle will not start.
Manually Releasing Tractor Spring
Brakes (Caging)
When air pressure in the system drops below approximately
43 P.S.I. (2.96 bar), the spring parking brakes will apply
automatically. To release the spring brakes, the air pressure
must be returned to 70 P.S.I. (4.83 bar). If the system cannot
be recharged and the vehicle must be moved, the spring
parking brakes can be released manually (caged).
To release the spring brakes, the actual spring in the brake
canisters must be mechanically compressed. A release stud,
or spring caging tool, must be used to manually compress the
brake chamber.
Never manually release (cage) the spring brakes before
the wheels are properly blocked. If the wheels are not
properly blocked before releasing the spring brakes, the
vehicle may move unexpectedly. This could result in
serious injury or death.
The following steps can be used to release the standard brake
chambers used on most Kalmar tractors. If your vehicle is
equipped with other optional brake chambers, refer to that
manufacturer's operation or service manual.
1. Shut the engine off and remove the key.
2. BLOCK ALL wheels front and rear to prevent the vehicle
from rolling forward and backward.
3. Determine whether the chamber has an internal (Figure 20)
or external (Figure 21) caging tool. Proceed to step 4 with
an external-mounted tool. See step 8 for internal types.
4. Remove the access plug from the brake canister.
5. Insert the caging tool into the access hole, "T" end first.
