Pneumatic System
The pneumatic system is crucial for efficient brake
operation.
NOTE: Before searching for parts, identify the type of cab
your unit is equipped with (cab over or
conventional). The mounting of some components
for the body depends on the type of cab
configuration.
To avoid problems with the air system of your vehicle
(especially in cold weather conditions), Labrie
Enviroquip Group strongly recommends draining the
M
INIMAX™ air tanks at the end of every workday and
prior to any maintenance.
To drain the air tanks, apply the following procedure:
1. Locate the drain valves on the air tanks (see Figure
7-1).
NOTE: Some trucks are equipped with more than one
drain valve.
2. Open the valves by turning them one-quarter turn
clockwise.
IMPORTANT: Before opening the valves, be sure to stay away from
the stream.
3. Leave the valves open until moisture is removed.
4. When all moisture has been drawn out, close the
valves by turning them one-quarter turn counter-
clockwise.
Caution
The operator must wear safety glasses to
protect his eyes against dust and suspended
matters. The operator must also stay away
from the stream to avoid potential injuries.
