Page 10 The jacks are not suitable for supporting lifted loads. Lifting more than one axle at a time is prohibited. Stepping on the load handling attachment is prohibited. Riding on the load handling attachment is prohibited. Use for other lifting operations is prohibited. Lifting with additional lifting gear is prohibited.
Page 11 pump has the ability to achieve higher hydraulic pressures and thus to lift heavier loads. In pneumatic-hydraulic jacks, the compressed air drives an air motor, which is firmly bolted to the hydraulic block. This oscillating pressure intensifier conveys the hydraulic oil. In rapid mode, the hydraulic oil in the tank is pressurised with compressed air, which displaces the hydraulic oil from the tank and allows the lifting piston to reach the load application point more quickly.
Page 12 Safety Features Relief Valve A pressure relief valve is installed between the pump and the check valve. This DBV limits the hydraulic pressure that can be generated by the pump, preventing excessive loads from being lifted. The DBV is adjusted to the load and set at the factory. The setting of the DBV must not be changed.

Page 41 10.2 General Safety Instructions for Safe Operation WARNING Pit jacks and gear jacks are not suitable for supporting the load over a long period of time. Work under a lifted load may only be carried out using suitable supports. Safety devices must not be by-passed or rendered unusable in any other way. Riding with the load or on the load-handling attachment is prohibited Climbing up the lifted vehicle is prohibited.
Page 42 (e.g. by lashing straps). As standard, the jacks are supplied with a simple support. For loads that cannot be lifted safely with this, MAHA can supply suitable load handling attachments. When using these, the corresponding operating instructions of the accessories must be observed.
Page 43 Ensure that the connection cable is plugged in. Switch on the main switch to make the jack ready for operation. The jack is immediately ready for use. 10.5 Raising WARNING The permissible load must not be exceeded. Load and jack must be observed by the operator during the entire lifting and lowering process.
Page 44 The hydraulic-pneumatically operated jack is lifted by pressing the correspon- ding button for load or rapid stroke. The pushbuttons are provided with auto- matic reset. When the buttons are released, the stroke movement stops automatically. An attached claw serves as a load-handling attachment. For special load application points on vehicles, other suitable mounts from our range of accessories can be fitted (support plate, transmission plate, axle traverse).
Page 45 Press button (B) to lift. The respective button is only active as long as it is held down (dead man's switch). When a run command is triggered, the cylinder runs at a constant speed. A rapid control does not exist for this jack. 10.6 Supporting WARNING...
Page 46 The lowering process is initiated by pressing the corresponding pushbutton. During the lowering process, the lowering speed can be changed via a rotary potentiometer. MAHA strongly recommends that the following procedure be followed when lowering to avoid damage to property and personal injury: Set rotary switch to “0”.
Page 47 WARNUNG Before removing the vehicle, the jacks must be in the lower home position to prevent damage to the jacks and vehicle. Drive out the vehicle only at walking speed and only if there are no persons in the pit or on the driveway. ATTENTION: Be careful when running vehicle engines.
Page 48 Troubleshooting WARNING • The relevant health and safety regulations must be observed. • Wear personal protective equipment. • Service work may only be carried out by authorised service technicians. • Repair, maintenance and setup work may only be carried out when the jack is at a standstill.

Page 53 Periodic and Recurring Inspections WARNING All inspections must be carried out in unloaded condition. Irrespective of the periodic inspections, subsequent inspections must be carried out by the operator and user at the specified intervals. Of course, the operator can entrust external experts with these inspections during the year. The same applies to the rectification of any defects identified.
Page 54 12.2 Weekly 12.2.1 Piston Rod The piston rod must be extended empty once a week (see also “Maintenance”) to bleed the jack. In this course, the piston rod must be inspected for damage. Damaged piston rods lead to leakage at seals. Damage to the piston rod allows cleaning agents and salt water to penetrate unhindered.
Page 55 12.3.2 Rollers Needle bearing Needle bearing Chassis roller Circlip Lubricating nipple, funnel inside and outside Track rollers must receive special attention, as they must support the entire load on the one hand and ensure easy movement of the jack and the chassis on the other.
Page 56 If necessary, the brake must be readjusted as described in section “Adjusting the Pit Jack brake”. 12.3.5 Prefilter Pneumatically operated pit jacks have a prefilter at the compressed air inlet, which is necessary to protect the control system. To check, disassemble the compressed air coupling and the internal Allen threaded pin behind it.
Page 57 Servicing Regular maintenance ensures the function and operational safety of the lift and contributes to its value retention. In order to ensure the safe operation and function of the lift, maintenance must be carried out at the latest after the intervals of the maintenance plan to the extent described.
