DANGER!
HIGH VOLTAGE!! Disconnect and/or lock out the electrical supply to
the power unit prior to any maintenance being performed.
1. Change oil once a year or when it materially darkens or feels gritty. Also, check oil
for the presence of water (oil will turn milky in color.)
2. NEVER TRY TO DISASSEMBLE OR REPAIR A PUMP IN THE FIELD. These
pumps are high-precision devices requiring extreme precision in fit-up. When one is
damaged, there is seldom anything that can be repaired in the field. It is also more
economical to replace a pump than to refit old parts with new parts.
3. The pin, or roller bushing should be replaced whenever excessive wear is detected.
The rollers are furnished with the pressed-in bushing as a unit part.
DANGER !
To avoid personal injury, NEVER go under the lift platform until the load is
removed and the scissors mechanism is securely blocked in the open
position.
