WARNINGS - SAFE USAGE INSTRUCTIONS
1. Study, understand and follow all instructions before
operating this jack.
2. The operator must ensure that the jack can be operated
without any danger to himself or others. Only operate
the jack when the vehicle can be fully observed.
3. Do not exceed rated capacity.
4. Use only on hard level surfaces.
5. The vehicle must be allowed to run freely during lifting
and lowering (without brakes and in neutral).
6. The jack is only to be used for partly lifting vehicles, and
for lifting engines, gearboxes and similar.
7. The load's gravity must be placed centrally; making sure
that it cannot drop or slide.
8. Lift only on areas of the vehicle that are specified by the
vehicle manufacturer, and only centrally on the lifting saddle.
9. Lifting device only. Immediately after lifting, support the
vehicle with support stands or support bridge.
10. Engine and gearboxes etc. must be fully lowered and
secured by straps or similar before transporting.
11. No person may remain in, on, or physically beneath a
load that is being jacked or is supported by a jack only.
12. Only original accessories and spare parts may be used.
13. No alterations may be made to this jack.
14. Failure to follow these warnings may result in personal
injury and/or property damage.
Assembly, GGD150F and GGD150U
Connect air supply on the left side, ¼" WRG, 8.5 – 12 bar,
350 l/min; 123 – 174 psi, 13 cfm/min. Hydraulic pressure =
310 bar.
Always use air supply with filter and oil-lubricator close to the
air outlet. Top capacity reaches at 8,5 bar.
Assembly, GGD150S
The pit jack is supplied with the cylinder separated from the
main trolley in order to permit lowering into the pit:
• Suspend the main trolley at an angle in (fig. 1) approved
slings (300 kg) using a crane or a forklift truck, and lower it
into the pit. Place the main trolley on a bearer at both sides,
about 10 cm above the ground.
• Unscrew the 4 loose screws 0232200 under the cylinder
carriage and remove console 5900250 (the console
opposite axle 5900232) (fig. 2).
• Suspend the cylinder by its handles at an angle with the
remaining console at the bottom. Edge the carriage into the
main trolley rail (fig. 3), and then carefully lower the cylinder
further until it is close to vertical (Warning: danger of
crushing!). Place the loose console in the rail (fig. 2), push
it sideways into the carriage (fig. 4) and remount 4 screws
0232200.
• OBS: Do NOT lift the complete pit jack by the cylinder
handles.
• Lift the complete pit jack using slings around the main
trolley and remove the bearers. Adjust the 4 side rollers to
fit the width of the pit (fig. 5). Make sure, that the pit jack
runs freely along the length of the pit.
The oil reservoir is plugged for transport: Remove the plug
from fitting 0243900 and attach air hose 9079883.
Connect air supply on the left side, ¼" WRG, 8.5 – 12 bar,
350 l/min; 123 – 174 psi, 13 cfm/min. Hydraulic pressure =
310 bar.
Always use air supply with filter and oil-lubricator close to the
air outlet. Top capacity reaches at 8,5 bar.

Use
The vehicle must be allowed to run freely during lifting and
lowering (without brakes and in neutral).
Lifting: Activate the pedal for pneumatic quick approach until
the lifting saddle is close to the lifting point. Then position the
jack to lift exactly on the lifting point specified by the vehicle
manufacturer. Make sure that the vehicle cannot slide. Then
start the air motor by applying more pressure on the pedal.
The manual pump can be used if the air supply is down.
Lifting engines and gearboxes: When lifting engines or
gearboxes etc. the manual pump can be useful for making
final adjustments.
Lowering: Make sure that the vehicle is allowed to run freely
(without brakes and in neutral). Then slowly turn the black
release knob counter clockwise.
Transport: Engines and gearboxes etc. must be fully
lowered and secured by straps or similar before transporting.
Locking of cylinder: on GGD150S and GGD150U with
movable cylinder, the cylinder can be locked using brake
lever 5900233.
Locking of main trolley: on GGD150S the main trolley can
be locked using a similar brake lever 5900233.
Noise emission: The A-weighted emission sound pressure
level does not exceed 80 db(A).
Maintenance
Maintenance and repair must always be carried out by
qualified personnel.
Never use high pressure cleaners or steam for cleaning.
The lifting cylinder must be protected against paint and sticky
rust preventive.
Remove the air hose before repair.
Bleeding: Following repair the hydraulic system needs to be
bled, at first the foot pump, then the cylinder:
• Pump the first cylinder stage (Ø 90 mm) some 100 mm up
against a small load (min. 500 kg, e.g. a forklift).
• To bleed the foot pump loosen the two screws 0230100
(dismount axle 9018400 momentarily to gain access to
the pump piston), and then pump the pedal until pure oil
emerges.
• To bleed the cylinder loosen screw 0230100 in the flange
joint and pump again until pure oil emerges.
• Remember to tighten the 3 screws again!
Daily: Inspect the jack for damage. Drain the air supply filter
and refill oil-lubricator if needed.
Monthly: Inspect for hydraulic leaks and verify the oil level.
Clean and grease the top of the piston rod. Clean and
grease the corresponding hole in saddles and accessories.
Oil the wheels with a few drops of oil.
Oil refill: Refill oil through oil plug 0247000 in the reservoir
tube. Check that the oil level with the rams fully down is up
to the oil plug. In the event of water in the oil, the oil must be
changed: empty the reservoir through plug 0200077 in the
bottom of the cylinder. Oil quantity is 9.5 l.
Use any good hydraulic oil of viscosity ISO VG 15. NEVER
USE BRAKE FLUID!
Safety Inspection
According to national legislation – at least once a year – the
jack must be inspected by a professional: damage, wear
and tear, adjustment of the safety valve, hoses, cylinder and
pump unit for leaks. Furthermore all safety labels must be
checked to ensure that they are legible.
