MAINTENANCE

Generally, the DBP Series DC Electric Scissor Lifts 

require very little maintenance.  Reasonable care will 

result in excellent trouble-free performance. 

WARNING!

Never go under or service lift with a load on the table 

or with the scissor mechanism unblocked. Always 

service the lift in a down position.

A.  

ROUTINE MAINTENANCE:

All routine maintenance should be performed monthly 

and can be performed on the standard DBP Series DC 

Electric Scissor Lifts in a lowered height position. Be-

fore performing any maintenance, disconnect the bat-

tery. Then raise the top over its center position, secure 

in place and perform the routine listed (1 through 7).

WARNING! 

Wood blocks should be cut to the proper length 

and be of a hard wood variety. Check for defects 

or damage to the blocks prior to each usage. These 

blocks are to be used only if the maintenance chock 

has been damaged or misplaced.

1). Check oil level. Add oil if necessary.

2). Check rollers for signs of wear. Replace if dam-

aged.

3). Check snap ring and shield. Replace if damaged.

4). Check hydraulic lines for damage or leaking. Replace 

if damaged.

5). Check for oil spots on the floor. Trace leaks to the 

proper fitting and tighten.

6). Check wiring for damage. Replace immediately if 

any sign of wear is evident.

7). Bearings on these lifts are permanently lubricated 

and require no servicing. Look for any signs of 

wear.

B. 

TROUBLESHOOTING MAINTENANCE:

LIFT WILL NOT MOVE

1. No operational noises:

a). Check power switch.

b). Check voltage at motor -- motor may have

failed.

2. Operational noises:

a). Lift may be overloaded or jammed. Check load

weight and obstructions.

b). Oil shortage -- reservoir low or oil line failure. 

Repair or replace.

3. Motor overheats:

a). Excessive cycle rate (15 per hour max.).

b). Low voltage -- check voltage at motor.

c). Oil starvation -- check filter in reservoir.

LIFT OPERATING SLOWLY

1. Up cycle:

a). Oil starvation -- check filter in reservoir.

b). Oil viscosity -- oil is too heavy or too thin.

c). Air in cylinder -- cycle lift with no load 2 times

and hold down button for 20 seconds after 

bottoming out on each cycle.

2. Down cycle: (single acting cylinders)
