Mpj 1S; Mpj 2S | Mpj 3S - MAHA MPJ Series Original Operating Instructions

During the lifting and lowering process, there must be no persons or objects in
the safety area of the load and pit jack.
Carefully position the load handling attachment on the load during the load
stroke and lift it free briefly.
Only lift the load after checking that it is safe to do so.
The vehicle must be able to move freely in the longitudinal direction of the
vehicle to prevent the load from slipping.

MPJ 1S

The manually driven pit jack is operated via plug-in pump levers. The distinction
between load and fast stroke is made as described above.
The hydraulically-pneumatically operated pit jack is raised by pressing the
corresponding button for load or rapid traverse. The buttons are equipped with
automatic reset. When the buttons are released, the lifting movement stops
automatically.
An attached claw serves as a load suspension device. For special load
application points on vehicles, other suitable mounts from our range of
accessories can be fitted (support plate, gear plate, axle cross member).

WARNING
Depending on the air pressure and the lift height reached, the piston rod
extends a little further after the button is released.
Risk of crushing between piston rod/load handling attachment and test vehicle.
In the standard version, the pit jacks are supplied with foot control.
The actuating elements for the load and rapid lift are located under a cover at
the base of the lift.
The fast approach stroke is located on the right-hand side of the operating field
and is indicated by a double arrow. It is used to quickly overcome the dead lift
to the vicinity of the lifting point.
From there, you can continue with the load lift. This is located on the left in the
operating field and is indicated by a simple arrow.
Sensitive approach to the load lifting point can also be achieved using the
optional foot pump. For this purpose, the foot pedal (J) can be inserted into the
foot pump (G) and secured against unintentional slipping out by means of a
locking pin.
If the pit jack is equipped with an optional manual control, it can also be used
for rapid and load lifting. The pushbuttons on the hand control for fast and load
lift are marked with a single arrow for load lift and a double arrow for fast lift,
just like the foot buttons. The rapid traverse is realized here by pressurizing the
hydraulic oil in the tank with compressed air and passing it through a valve that
allows a larger hydraulic volume flow.
