Short distance towing when the engine is
inoperative
Chock the wheels to prevent the planer
from moving when the brakes are hydraulically
disengaged.
Open the two foot boards on the platform and
found the propel system by-pass ball valve (1)
which handle should be in line with pipeline to
put the system in working mode. (by-pass valve
(1) in vertical position is By Pass Mode)
By-pass mode means that A and B sides on the
pump are freely connected to the pressure side.
This function enables a machine to be moved
without the drive shaft rotating.
Manual brake release:
- Release the nut (4) of the towing valve; screw
the adjusting screw (3) to the lowest position.
- Press the pump handle (5) until the brake
pressure was released completely. (About
3bar).
- Rotate the towing valve (1) from horizontal
position to vertical position.
- After finishing towing the planer, set the valve
to original position.
The planer can now be towed.
After towing, it is important to reset the towing
valve (1) and the brake release to working mode.
Disengage the by-pass mode by turn back the ball
valve handle (1) to horizontal position and turn
back the adjusting screw (3).
The machine must not be moved at a speed
higher than 0.5 km/h, and no more than 300
meters. Otherwise there is a risk of damaging the
drives. Make sure to reset the towing valves (by
turning them three turns clockwise) after towing.
