4.2 POWER DRIVE STARTUP
4.2.1 Gas Engine Startup
1. Handle fuel with care. It is highly flammable. Use approved fuel container. Fill tank outdoors in a well ventilated
area on a bare surface. Make sure the gas caps on the engine and fuel can are properly tightened. Ensure the fuel
storage area is at least 10 feet from the power drive before starting the engine. Never remove the fuel cap or add fuel
to a running or hot engine. Let the engine cool 2 minutes before fueling.
2. Check oil level in both the crankcase and reducer. Always add oil with the power drive on the level. Follow
manufacturer specifications on type and amount of oil to add. Refer to the manufacturer’s instructions and to Chapter
6 of this manual.
6

CAUTION:
GASOLINE ENGINES ARE SHIPPED WITHOUT OIL IN THE CRANKCASE. ATTEMPTING
TO RUN THE ENGINE WITHOUT FILLING THE CRANKCASE AND TOPPING OFF THE
REDUCER WITH OIL WILL CAUSE SERIOUS ENGINE DAMAGE AND MAY VOID THE
WARRANTY.
3. Check the engine air cleaner and air intake screen for dirt or obstruction. Clean as required.
4. Move choke control to choke or start position and move throttle to half throttle position to start a cold engine. Move
choke control to run position slowly after engine starts and allow a warm up. The choke must be in the run position
during normal operation or when starting a warm engine. Placing the throttle in the slow position before stopping the
engine permits a cooling period.
WARNING:
DO NOT USE IN WET CONDITIONS.
4.2.2 RAISING AND LOWERING THE LOAD
WARNING:
SECURE THE LOAD BEFORE LIFTING.
WARNING:
DO NOT OPERATE HOIST WHEN BRAKE ROPE IS WET
1. Before operating the clutch and brake levers, install the provided lever handles using the provided spring locks.
Install the #25 handle extension shown in Figure 8-1 on the clutch lever handle using the nut and bolt provided.
2. Make a few “dry runs” (no load), to test power drive, hoisting operation, and controls.
WARNING:
NEVER STAND IN-LINE WITH THE RAISING OR LOWERING OF THE PLATFORM AT
EITHER THE TOP OR BOTTOM OF THE HOIST TRACK.
3. To raise the load, first advance the throttle to increase the engine speed. Then lift the left clutch handle slowly with a
smooth upward motion. This automatically tightens the drive belt and releases the brake, permitting the platform to
roll up the track.
4. When the platform reaches the top of the track, release the clutch lever. This action stops the platform and
automatically applies the brake, which holds the load and platform. The load will now roll automatically off the
platform onto the roller angle guide if you are using one.
WARNING:
KEEP OUT FROM UNDER A RAISED LOAD.
7

WARNING:
IF THE ENGINE FAILS DURING OPERATION, RELEASE CONTROL LEVERS TO PREVENT
LOAD FROM FALLING.
5. Do not allow the platform to jam against the spring stops on the top bracket. The drive belt may jam in the drum
sheave, preventing the lowering of the platform.
WARNING:
DO NOT REMOVE MATERIAL FROM THE HOIST UNTIL IT HAS STOPPED
COMPLETELY.
6. Lift the brake lever slowly to lower platform to the ground. Lowering speed for SAFE operation should not
exceed 50 feet/minute. Continue to decelerate the platform as it nears the ground to prevent damage to platform or
track. Do not allow the platform to strike the track shoes on reaching the bottom of the track. If necessary,
extra downward pressure on the brake lever can be applied to stop the load.
WARNING:
AVOID SUDDEN BRAKING WHEN HANDLING A LOAD.
7. Check the hoist periodically during operation. Do not attempt to make adjustments during operation.
WARNING:
KEEP ALL BODY PARTS CLEAR OF MOVING PARTS.
4.3 PREPARING POWER DRIVE FOR SHUTDOWN
At the end of operation, secure the equipment to prevent unauthorized use. Never assume you will find the equipment in
the same condition that you left it. Proceed as follows:
1. Ensure that all lifting tension has been removed from the wire rope.
2. Shut off power drive and take necessary action to prevent its unauthorized use.
3. If the power drive is being permanently disassembled, at the end of a project for example, follow the detailed
disassembly procedures in Chapter 5.

6 INSPECTION AND MAINTENANCE
6.1 GENERAL MAINTENANCE RULES
1. Proper maintenance of the power drive and related equipment consists of adhering to all the guidelines given in this
chapter and in the Pre-Hoisting Checklist in the front of this manual. Proper maintenance is required to maintain the
system in good condition, which is defined as each part being free of rust or other corrosion, bends, breaks, or other
defects.
2. Review and follow all the safety rules given in Chapter 1 before attempting any maintenance.
3. Only authorized personnel should be allowed in the maintenance area. Authorized personnel are the trained people
as defined below and their supervision.
4. Repairs must be made only by trained personnel. A trained person is one who has read and thoroughly understands
this instruction manual and related equipment manuals and, through training and experience, has shown knowledge
regarding the safe operational procedures.
WARNING:
WEAR HEAVY LEATHER GLOVES WHEN HANDLING WIRE ROPE. INSUFFICIENT HAND
PROTECTION WHEN HANDLING WIRE ROPE CAN CAUSE SERIOUS PERSONAL INJURY.
5. Do not weld or otherwise modify the power drive. Such alterations may weaken the structural integrity of the power
drive and invalidate your warranty.
WARNING:
DURING ANY ERECTION, MAINTENANCE, OR REPAIR PROCEDURES, DO NOT ATTEMPT
ANY HOISTING. THIS CAN CAUSE EQUIPMENT DAMAGE AND/OR SERIOUS PERSONAL
INJURY.
WARNING:
EXCEPT FOR MAINTENANCE AND REPAIRS THAT CANNOT BE DONE OTHERWISE,
SHUT DOWN AND LOCK OUT THE POWER DRIVE TO PREVENT ACCIDENTAL
STARTUP.
WARNING:
NEVER CLIMB THE TRACK TO DO MAINTENANCE. THIS CAN LEAD TO SERIOUS
PERSONAL INJURY.
6.2 INITIAL INSPECTION
Power drive assembly and disassembly, must be done by trained personnel only as defined in Section 6.1. Each time after
setting up the hoist and before placing it in service, all parts of the hoist structure, power drive, and other equipment must
be thoroughly inspected by trained personnel as described in the remainder of this chapter and related equipment
manuals.
6.3 DAILY INSPECTION
It is important that all the maintenance procedures outlined in the Pre-Hoisting Checklist in the front of this manual be
done daily. Details on inspecting the wire rope are given in Section 6.9. All broken, worn or defective parts must be
repaired or replaced before startup.
10

6.4 CLUTCH-BRAKE ADJUSTMENT
The combination clutch and brake actions to raise rated loads with the clutch handle are adjusted at the factory. If field
adjustments are needed, proceed as follows. Refer to Figure 6-1 for adjustment details.
1. The Dacron brake holds the load when the clutch lever is released. If the load drifts down, tighten the nut at the base
of the #24 spring to compress this spring. This increases the initial load on the brake lever. Note that the #24 spring
should be compressed to about 3 1/8 ±1/16 inches with about 3/8 inches movement on the bottom edge of the #8
brake differential.
2. Excessive tightening fully compresses the spring and the brake will not release. There should always be a 1/32 inch
gap between brake lever #3 and nuts “B” and “C”. If this “play” in brake lever #3 is absent, you can flex the rod and
break it.
3. If the load still drifts down move the brake rope end “D” from the outer hole to the inner hole on the #8 brake
differential. As the Dacron brake wears, the brake lever may need adjusting to bring the lever up to its proper
operating position. Alternate holes are provided in the brake rope ends for this purpose.
4. When properly adjusted, the brake will release before the #10 clutch spring is entirely compressed. Gap “A” is
widened or narrowed by screwing or unscrewing, respectively, nuts “B” and “C”. Make this adjustment carefully. If
there is no gap “A”, the brake will release before the clutch belt is tightened. This will cause a sudden jerking before
the clutch belt is tightened, resulting in an overload on the hoist, wire rope, and track. The clutch can be engaged
sooner to help avoid this overloading by tightening the top nut on the #10 clutch spring shown in Figure 8-1. The
clutch spring is preset at the factory to a compressed height of 1 3/4 inches.
11
Figure 6-1.
Clutch-Brake Adjustment Detail

6.5 SAFETY HOOKS
The hook to which the power drive wire rope is attached will be either the platform safety hook on the PL250 & PRO200
models or the top bracket hook on the PL400 & PRO400 models. If these hooks should become broken, bent, or
disassembled, they should be replaced immediately.
6.6 OILING MECHANICAL PARTS
The main bearings (shown as #18 in Figure 8-1) are lubricated for life and need no attention. Oil all pivots and linkage
joints occasionally.
6.7 ENGINE OIL REQUIREMENTS
CAUTION:
GASOLINE ENGINES ARE SHIPPED WITHOUT OIL IN THE CRANKCASE.
ATTEMPTING TO RUN THE ENGINE WITHOUT FILLING THE CRANKCASE AND
REDUCER WITH OIL WILL CAUSE SERIOUS ENGINE DAMAGE AND MAY VOID THE
WARRANTY.
6.7.1 Briggs & Stratton Engines
Before starting the engine, check and add oil according to the viscosity chart shown in your engine manual. Use a high
quality detergent oil classified “For Service SF, SG, SH,” such as SAE 30 oil. Do NOT use special additives with
recommended oils. Do NOT mix oil with gasoline.
Add oil and fill to overflowing as shown in your engine manual. Oil capacity is about 2/3 quart (21 ounces or 0.6 liter).
The gear reducer must also be filled with oil. To fill, pour SAE 30 oil into oil fill hole until it runs out the level check
hole. Refer to the engine manual for details on filling the gear reducer.
After filling with or changing oil, start and run the engine at idle for 30 seconds. Shut engine off. Wait 30 seconds and
check oil level.
The engine itself (not the power drive) must be in the upright (level) position when filling and checking oil.
12

13
6.8 ENGINE MAINTENANCE
The engine is guaranteed against defects by its manufacturer. Follow the manufacturer’s instructions for proper
lubrication and maintenance. The following table summarizes the type and frequency of maintenance required.
Follow the hourly or calendar intervals, whichever occurs first. For repairs, contact the nearest authorized service
center.
TYPE OF MAINTENANCE FREQUENCY OF SERVICE
Check oil level Every 5 hours or daily
Change oil After first 5 hours, then after every 50
hours or every season. Change oil every
25 hours when operating under heavy
load or in high temperatures.
Change oil in gear reduction 100 hours or every season
Service air cleaner pre-cleaner if equipped, or air cleaner cartridge if not
equipped with pre-cleaner. 25 hours or every season. Clean more often under dusty conditions or when
airborne debris is present. Replace air
cleaner parts if very dirty.
Service air cleaner cartridge if equipped with pre-cleaner. 100 hours or every season. Clean more
often under dusty conditions or when
airborne debris is present. Replace air
cleaner parts if very dirty.
Clean cooling system. 100 hours or every season. Clean more
often under dusty conditions or when
airborne debris is present. Replace air
cleaner parts if very dirty.
Inspect spark arrester, if equipped. 50 hours or every season.
Replace or clean spark plug. 100 hours or every season.
Clean combustion chamber deposits. 100-300 hours.

6.9 WIRE ROPE INSPECTION PROCEDURE
Inspect the wire rope prior to each use and at least daily for signs of wear, damage, or pinching. Inspect the entire wire
rope working length. Thoroughly inspect the rope sections that pass over sheaves or drums, or that make opposing turns.
Inspect wire rope and end attachments carefully. While inspecting, examine sheaves, guards, guides, drums, flanges, and
other surfaces contacting wire rope during operation. Correct any condition harming the rope in use or other damage or
worn surfaces at this time.
Remove or replace immediately wire rope with one or more of the following defects:
1. Corrosion
2. Broken wires:
(a) One or more valley breaks. A valley break is a wire break occurring in the valley between two adjacent strands.
(b) Six randomly distributed broken wires in one rope lay. A rope lay is the length of rope along which one strand
makes a complete revolution around the rope. See Figure 6-2. Keeping the rope clean and wound evenly on the
drum will increase its life and efficiency.
3. Abrasion: Scrubbing, flattening or peening causing loss of more than one-third of the original diameter of the outside
wires.
4. Kinking: Severe kinking, crushing, bird caging or other damage causing distortion of the rope structure. Bird caging
is a bulging in the wire rope caused by the individual wires becoming untwisted. This untwisting of individual wires
is usually caused by impact loading on the wire rope (such as a sudden stop).
5. Heat damage: Evidence of any heat damage caused by a torch or by contact with electrical wires.
6. Reduction of more than 1/64 inch from a nominal 5/16-inch or less diameter wire rope.

6.10 REPLACING POWER DRIVE WIRE ROPE
Each end of the hoist wire rope is equipped with loops. The small loop is attached to the #17 brake sheave (see Figure 6-
3) by passing it through the hole and bending it back against the pull or load. It is snubbed over the web of the sheave
and fastened to the sheave with the screw provided. The large loop is used for attaching loads with a shackle and hook.
On platform units, the hook is mounted on the platform or top bracket, and the loop is slipped over the hook.

7TROUBLESHOOTING
The following chart is intended to assist with troubleshooting the power drive. While not all inclusive, the chart outlines
the most common causes of a problem and the recommended course of action.
The troubleshooting guide for the associated platform hoist is in the instruction manual specifically for that unit.
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
Power 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.
Hoist 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—adjust
as described in Chapter 6.
Clutch not properly adjusted—adjust as described in Chapter 6.
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.
Engine speed too slow—increase throttling.
Too much wire rope on drum—hoisting capacity decreases as
wire rope diameter increases.
Engine stalls when clutch handle is lifted. Brake is releasing before clutch belt is tightened—close the gap
by unscrewing nuts “B” and “C” to lower brake lever as
described in Chapter 6.
Power Drive will not lower platform. 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. Then release the jammed belt by
inserting a screw driver between the belt and the sheave groove.
Load drifts down. Spring #24 as shown in Figure 6-1 needs compressing—tighten
the nut as described in Chapter 6.
Brake rope end “D” needs adjusting—move from the outer hole
to the inner hole on the brake differential.
