Aerial working platform can be used for maintenance, installation, painting or others. When we using
the lifter, we need to notice the routine maintenance of scissor man lift.
1, Aerial work platform through after 200 hours of operation, replace the hydraulic oil and clean the
tank, replace the filter. Under normal circumstances, pls clean oil box once every six months,
using the occasion in more sand dust, oil change intervals should be shortened as appropriate.
2, The hydraulic system uses hydraulic oil must be kept clean at a constant temperature of 0-40 ℃
areas, usually using ordinary HL-N46 hydraulic oil. On the temperature difference between the
relatively large area, low-temperature hydraulic oil is recommended for winter use.
3, Self-propelled scissor lift after initial use or the use of long-term storage, so that the
agencies should load repeated action several times to exhaust air in the hydraulic system, tubing
joints can loosen the emission of air, if necessary, and then put the connector and tighten.
4, The relief valve adjustment It is set to vent pressure relief valve of the hydraulic system of
16MPa, when the system pressure fluctuations or foreign objects stuck relief valve core, the relief
valve must be cleaned to adjust, under normal circumstances, Panasonic relief valve plug guard,
increasing pressure from right-handed plug system with a flat, whereas the pressure, is reduced,
such as stuck, shall release the plug completely, pour the spool and spring cleaning and seat
together, and then re-install and adjust the pressure to the predetermined value.
5, The adjustment of spill valve In the course of scissor structure movements, such as the
the emergence of too fast or too slow can be achieved by adjusting the spill valve so that the lifter
movements smooth, twist the plug clockwise to reduce speed, and vice versa counterclockwise to
increase speed, tone and tighten after and cap.
6, Regularly check the oil line hard pipe, hose without abnormal deformation damage, all fittings
and operating valve interface leaks oil, found the problem promptly.
7, Each of the platform relative to the moving parts, should be strictly in accordance with the
8, Electric scissor lift should be parked in the garage, the open place should cover tarps. When the
platform is not used for a long time, should be kept sealed. And check once a month, according to
the provisions of the tires, every month there should be a platform no-load operation and check
the operation of the agencies, identify problems in time.
9, Lubrication of the periodic table
Daily or refueling Check the parts are good or bad
Check hydraulic oil level and color
Every 250 hours or 3 months Change lubricating oil
Every 500 hours or 6 months Check tubes, pipes, and valve
Every 1000 hours or 1-year Change hydraulic oil
Grease rotation bearing and wear pads
Every 2000 hours or 2 years Check hydraulic tank, lid, and vent
Note: Maintain the chassis according to the chassis’ service manual
