2 Description
2.1 Usage, Applications
The TRUCKLIFT 8 / TRUCKLIFT 10 is a device for lifting motor vehicles up to a maximum gross
weight of 8,000 kg / 10000 kg, with a maximum load of 6000 kg / 6600 kg permitted on any pair
of columns. The maximum lifting height of the unit is 2,1 m, making it easy to work on the
underside of the vehicle, even for taller staff members.
TRUCKLIFT is designed primarily for lifting vans. However, the vehicle tracks can easily be
adjusted for lifting normal cars as well.
The lift must be installed and prepared for operation by a properly trained technician.
Structural and technical alterations to the lift are prohibited.
Always observe the detailed operating and service instructions provided.

4.2 Vehicle Tracks
The vehicle tracks can be moved laterally on the
crossbars to adjust the width to match the track width
of the vehicle to be lifted. Normally, you will only need
to adjust the left track.
Track to be adjusted
To adjust the track width, first remove the retaining
pins at the front and rear. Then move the track in the
desired direction by inserting a lever in the retaining
lug and levering against one of the holes in the
perforated section below. This must be done both at
the front and the rear, otherwise the track will not be
straight.
Adjusting the track
After adjusting the track position you must
secure it again with the retaining pins!
Front retaining pin
You do not have to adjust the other track, but you can
if you wish, for example in order to centre a vehicle
over a working pit. To do this, you must first unscrew
the retaining disks on the two retaining pins, and then
unscrew and remove the pins themselves. You can
then adjust the position of the track. Since this only
needs to be done once, no leverage aids are provided.
Fixed track"
After you have adjusted the track position you must
replace the retaining pins.

The control console is mounted on lifting column 1.
The main switch is on the side of the console. Turn
this switch to position 1 to turn on the power. The lift is
then ready for operation.
The main switch doubles as the
emergency off switch. In emergencies, simply turn
the switch to the 0 position to switch off the lift!

Lower the lift (see Lowering) until it stops
automatically in its starting position.
Drive the vehicle onto the lift tracks and stop so that it
is centred between the end columns.
The vehicle tracks of the lift must be

4.7 Locking the Lift to Prevent Unauthorised Operation
When the lift is not being used you should

5 Maintenance, Troubleshooting
5.1 Maintenance
Regular maintenance is necessary to ensure reliable operation of the lift and a long service life.
a) The support arm extension and the
support disc threading should be well
greased. It is recommended to use
lithium soap grease.
b) The oil level of the oil pan should be
checked quarterly. It is located on the
carriage slides behind the spindle
cover sheet. (see the upper part of the
diagram to the right) The pan should
have at least 5 mm of oil in it. If the oil
is not up to this level refill it. The neck
of the oil can be directly applied
through the brush cover of the column.

Trucklift Maintenance, Troubleshooting
c) Wear and tear on the support nut must
be checked annually. Remove the
plastic cap from the spindle cover
sheet and move the carriage slides so
that the control drill holes lines up with
the window.
If there is no visible gap this is an
indicatioin that the support nut is worn
down beyond the permissable limit.
The support nut must be replaced. The
gap is approximately 2 mm. ex factory.
When the wear limit is reached the
lift must be shut down until the
bearing nuts have been replaced.
Lock the main switch to ensure that
nobody can use the machine .
5.2 Repair Notes
Only trained, skilled electricians are allowed to check impulse sensor and proximity
switches.
Immediately contact your MAHA dealer or the MAHA service center when there are problems
with impulse sensors or proximity switches.
Unskilled work on electrical parts of the lifting platform can be life threatening.
The main switch should be switched off and secured before any repair work or
malfunction troubleshooting is done on the lift!
Malfunctions due to unskilled repair or adjustment work are not covered by the warranty.

5.3 Troubleshooting Checklist
The following checklist will help your service technicians to locate faults in the event of
problems.
Problem Possible cause Remedy
When lifting, lift stops of its

Lift stops in the upper
position. After pressing the
RESET button followed by
the "Lower" button, all
motors activate briefly and
then stop.(see ill. on next
page)
a) Excessive load on the lift.
b) The distance between the
pulse encoder and the drive
pulley is too great.
a) The lift has run into an
obstacle, lifting out the
jackscrew.
b) The distance between
the pulse encoder and the
drive pulley is too
great.
No signals from the upper pulse
encoders.
a) Check whether the load
exceeds the rated maximum
lifting capacity. Check the
jackscrew lubrication and the
tension of the toothed drive
belt.
b) Check impulse encoder
distance (have it corrected, if
necessary).
Lifting should then be possible
again after lowering the lift by at
least 2 cm.
a) Remove the obstacle.
b) Check the upper pulse
encoder.
Lowering should then be
possible again after raising the
lift by at least 5 cm.
Check the upper pulse
encoders.
When the "Lift" button is
pressed the motors
activate again briefly and
then stop.
Pressing the buttons again
produces no further
reaction from the lift.

board lights up after about
5 seconds.(see ill. on next

The lift stops at a height of
approx. 260 mm

The lift stops at a height of
approx. 400 mm

a) The distance between the
catch nuts and the jackscrew
bearing nuts is too small.
b) A proximity switch is defective
or its setting is incorrect.
No signal pulse from the

a) Check the wear of the bearing
nuts.
b) Check the distance between

(Call MAHA-Service Dept.).
Check the distance between the

The lift can only be moved
to its lower starting
position.
Lifting is no longer
possible.
At the beginning of lifting
the lift stops and the power
supply circuit breaker trips.
Neither lifting nor lowering
are possible.
A bearing nut is broken and the
load is being borne by the catch
nut.
All motors are starting up
simultaneously. This causes a
voltage peak that trips the circuit
breaker
DIP switch 4 is set to "ON".(see
ill. on next page)
Have the bearing nut repaired.
Shut down the lift and
lock the main switch!
Change the setting of DIP switch
4 on the control PCB to
"OFF".(see ill. on next page).
This starts the motors in a
staggered sequence.
