TEST METHOD
A bench test should be conducted for strict testing, but as it is generally impossible in practical service
operation, install the oil pump on the vehicle and judge the oil pump discharge performance by means of
cylinder operation.
• Check that the battery charge is sufficient by observing the battery charge indicators
• Check that the oil control valve set relief pressure is as specified
• Measure the time of full stroke of the lift cylinder, with the hydraulic oil temperature at 50~55°C
(122~ 131°F), and calculate the lifting speed; however, due to soft start by the lifting logic unit, lifting
speed is 10 ~ 20 mm/sec lower than the value obtained from the table. The lifting speed can be
calculated more accurately by measuring the full stroke operation time excluding the soft start period
The lifting speed may differ depending on the conditions of the battery, hydraulic oil temperature and mast
adjustment.
The values below are based on a certain condition.
Lift relief pressure
175 - 235 bar
