• Return the pump to the horizontal position and remove the threaded nozzle with the silicone hose.
• Fill the tank with HLP 46 hydraulic oil to the "Max" marking (approximately 3 litres). The pump must first be
bled before tools and cylinders are used for first time.
• To bleed the pump, insert the supplied coupler on the end coupling of the hose package.
• Activate the pump and allow the supplied oil to flow back into the opened tank. To do this, tilt the hydraulic
pump slightly to allow the trapped air bubbles to dissipate easier.
• Allow the aggregate to supply oil for approximately 60-120 seconds. Once the oil flows uniformly and
without air bubbles or interruptions from the hose, the pump is bled adequately and ready for further use.
• Remove the coupler from the hose.
• Finally, check the oil level.
• For further use of the pump, close the tank opening with the ventilation screw,
otherwise with the screw plug.
! caution!
in particular, when performing an oil change, escaping hydraulic oil can endanger
the environment!
• collect any escaped hydraulic oil and prevent it from entering the sewage system or from
contaminating the surface water and groundwater.
11. maintenance and insPection
The user is obliged to maintain and service the hydraulic pump in accordance with the details in the
operating instructions and the country-specific standards and regulations.
The maintenance intervals are classified in accordance with the recommended frequency of execution.
caution!
!
while the hydraulic pump is switched on, there is the danger of the connected unit starting,
e.g. by an inadvertent actuation of the foot-operated switch, and so risk of injury in the area
of the unit components.
• For all maintenance and repair work, ensure that the mains plug of the pump has been
withdrawn to prevent inadvertent starting.
Before every use...
• Visually inspect the hydraulic pump and hoses as well as the foot-operated switch for damage.
• Check all electrical and hydraulic connection lines for damage.
• Check the correct, tight fit of the hydraulic couplings.
• Check the correct function of the foot-operated switch.
once after 50 operating hours...
• Perform a complete oil change with 3 litres of HLP 46 hydraulic oil (see section 10 "Oil change").
weekly...
• Clean the motor space externally with dry compressed air.
• Check the correct function of the emergency stop switch of the connected tool for activated pump.
• Check the correct function of the safety shutdown at the foot-operated switch.
warning!
!
there is the risk of injury caused by defective safety equipment.
• if when checking the safety shutdown, the pump is not shutdown, bring the pump to a
standstill immediately.
• have the safety shutdown equipment repaired without delay.
• recommission the pump only after the repair work has been completed.
monthly...
• Check the oil level and, when necessary, add HLP 46 hydraulic oil to the "Max" marking.
• Check the markings and warning signs on the pump for readability and damage, and replace, when necessary
(see section 2.2 "Symbols on the pump").
