TROUBLESHOOTING
The following chart is intended to assist with troubleshooting the PRO Drive. While not all inclusive, the chart outlines
the most common causes of a problem and the recommended course of action.
SYMPTOM
CAUSE AND CORRECTIVE ACTION
Gas engine will not start
Air filter clogged—replace filter
1.
Too much oil in crankcase—pistons can’t come back down
which can saturate air filter with oil.
2.
Tipping the engine, allowing oil to run up the relief tube.
3.
Air filter dirty after normal use.
Clogged fuel line—replace fuel filter.
Fuel shut off in OFF position—turn ON
Engine switch in OFF position—turn ON
Honda engine low oil trip—engine is positioned at an angle.
Honda engine must be level to start. Check oil level.
Electric motor will not start
Blown fuse or tripped circuit breaker—replace or reset as
required.
Loose connections—check all plug and switch wiring
connections
PRO Drive won’t lift load or is lifting it very
slowly
No oil in engine to build compression—must add oil. Check
piston rings for compression.
PRO Drive attempting to lift more than stated capacity of unit—
check capacity rating and reduce load weight as needed
Brake is dragging which may cause a “squealing” noise.
Platform not moving freely—check for track obstructions or
block and wire rope malfunctions
Engine related problems—refer to beginning of this table.
Reference to manufacturer’s instruction manual may be
necessary.
On electric motors, extension cord too long which can cause
reduced voltage input—shorter cord must be used
Engine speed too slow—increase throttling.
Too much wire rope on drum—hoisting capacity decreases as
wire rope diameter increases.
Engine stalls when operator handle is lifted.
Brake is releasing before clutch belt is tightened.
Platform will not lower.
Platform has been allowed to jam against the spring stops on the
top bracket causing the drive belt to jam in the drum sheave—
shut off the gas engine or electric motor. Then release the
jammed belt by inserting a screwdriver between the belt and the
sheave groove.
