handle to press down, so that the pressure oil in the small oil pump pushes the one-way valve (3)
into the large oil cylinder (6) and pushes the plunger rod to rise and lift, so that the fork moves
continuously up and down the handle. Up, when the handle stops operating the fork, it stops at a
certain position. Slowly turn left to loosen the pressure oil in the cylinder of the unloading valve
(5) and leave it back to the mailbox (7) to reduce the cargo.
5. It should be used on hard and smooth pavement to prevent collision with steel plates, corners,
iron scraps and other objects damaging the wheels; during the lifting of goods, no people are
allowed to stand nearby, the goods should be laid down during maintenance and adjustment,
and the height of fork should be lowered as far as possible when carrying goods.
6. The oil tank should be filled with filtered No. 10 mechanical oil according to the regulations.
When the temperature is below - 15 degrees in winter in alpine areas, N32 low pour point
hydraulic oil should be used. In addition, according to the climatic characteristics of the region,
each manufacturer should change the lubricating grease of the rotating joints and bearings by
itself.
Troubleshooting
