Skilled personnel only is allowed to perform the operations
Daily checking items
The user must perform daily check. Daily check of safety system is very important – the discovery of device failure before action
could save your time and prevent you from great loss, injury or casualty.
• Always wipe clean,keep the machine clean.
• Clear barriers and ground oil,keep the working condition clean.
•
Check the integrity of each safety devices,ensure the motion is flexible and reliable.
• Check the reliability of limit switch motion.
• Check whether oil/air leakage of the machine exist.
Weekly checking items
• All bearings and hinges on this machine must be lubricated once a week by using an oiler
• Check the working conditions of safety parts.
• Check the amount of oil left in the oil tank. Oil is enough if the carriage can be raised to highest position. Otherwise, oil is
insufficient.
• Check whether the expansion bolts well anchored.
Monthly checking items
• The safety gear, the upper and lower sliding blocks and other movable parts must be lubricated one month.
• Check whether the foundation bolts well anchored.
• Check the abrasion and leakage of oil/air hose.
Yearly checking items
• The hydraulic oil must be replaced one time each year. The oil level should always be kept at upper limit position.
• Check abrasion and damage of all the active parts.
• Check the lubrication of roller. Lubricate it if drag phenomenon exist.
The machine should be lower to the lowest position when replace hydraulic oil, then let the old oil out, and should be filtering
the hydraulic oil. Each team checks the agility and reliability of pneumatic safety equipment.
Storage after use
When the machine does not use for a long time:
• Cut off the power supply and air source and lubricate all the active parts.
• Drain the hydraulic oil of oil cylinder,oil hose and oil tank.
• Sheathe the machine with dust-proof cover.
9 Trouble shooting
Failure phenomena
Cause
Resolution
The motor does not run
in lifting operation.
Connection of power supply wires is not
correct.
Check and correct wire connection
The AC contactor in the circuit of the motor
does not pick up.
If the motor operates when forcing the contactor
down with an isolation rod, check the control
circuit.
If the voltage at two ends of the contactor coil is
normal, replace the contactor.
The limit switch is not closed.
Check the limit switch, wires and adjust or
replace the limit switch.
