Page 5: Product Description
PRODUCT DESCRIPTION PP700 is a high-pressure hydraulic power pack that can be powered by a 2,2-kW electric motor 230V/110V (PP700-E) or by a 3,6-kW petrol engine (PP700-S). The machine has been engineered to power high pressure tools or hydraulic cylinders, the hydraulic pressure can reach 700 bar and can be easily reduced or adjusted by using the relief valve integrated with the machine. -
Page 6: Technical Characteristics
NOTE: The regulation screws of both valves 4-5 must be secured by the locknut to prevent from get lost due to vibration and consequently change the pressure regulations. The "MAX PRESSURE" and "CUT-OFF" valves have been adjusted by TEHMA to the maximum working pressure that can be accepted by its tools. -

Page 16: Start And Use Or The Power Pack
START AND USE COLD START THE POWER PACK SHOULD BE PROTECTED FROM BAD WEATHER AND TOO HARD CLIMATES. THE ENGINE COULD BE QUICKLY DAMAGED IF THE MACHINE IS LEFT EXPOSED TO RAIN AND LOW TEMPERATURES WITHOUT PROTECTION. WHEN THE MACHINE IS NOT USED, IT SHOULD BE STORED IN A DRY AND WARM PLACE REPAIRED FROM RAIN AND DAMPNESS. -
Page 17: End Of Operations
valve or trigger is free and released in its OFF to avoid unwanted activation; control that the return spring of the tool trigger is operative and efficient for avoiding an accidental starting. 3. Connect the flexible hoses to the power pack ( engine and flow control lever must be OFF)..and to the tool 4. -
Page 18: Maintenance And Care
The pressure gauge located on the valve top always indicates the pressure used or reached by the tool during its use. The "MAX PRESSURE" and "CUT-OFF" valves have been adjusted by TEHMA to the maximum working pressure that can be accepted by its tools. -

8. Try rotating the central distribution lever in the central position and then again on the previous channel to check the correct adjustment of the "CUT-OFF" valve. NOTE: a correct calibration implies that the pressure rises rapidly from 0 to the previously set pressure and once this limit is reached, it drops again to 50-100 bar. -
Page 20: Periodical Controls And Substitution Of Wear Out Parts
PERIODIC CONTROLS AND SUBSTITUTION OF WORN PARTS • EVERY TIME THE EQUIPMENT IS USED: 1. Control the hydraulic oil level 2. Control the level of the engine oil (or make the proper maintenance as specified in the manual of the engine manufacturer). 3. -
