   briefly create excess load causing product failure.

3. Do not operate when load is not centered underneath.

4. Do not operate hoist with twisted, kinked, or damaged wire rope.
   Inspect wire rope carefully before every use.

5. Do not operate a damaged or malfunctioning hoist. Inspect hoist carefully and test operation before every use.

6. Do not lift people or lift loads over people.
   Falling loads can injure or kill people.
   Do not use as elevator.

7. Do not operate with rope not centered in its groove.

8. Do not remove or cover warning labels and/ or tags. These carry important safety information.
   If unreadable or missing, contact Harbor Freight Tools for a replacement.

9. Do not lift animals or use for aircraft purposes.

10. The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be built into this product, but must be supplied by the operator.

Installation Specific Safety Information

1. The supporting structure the hoist is mounted to (including trolley, monorail, or crane) must be designed to withstand the loads and forces imposed by the hoist for the rated load.
2. Install in location that allows the operator to move and stay clear of the load.
3. Locate pendant controls at a convenient level above the operating floor.
4. Do not install where the load hook can be lowered beyond the rated hook travel under normal operating conditions.
5. DO NOT USE AN EXTENSION CORD. An extension cord would cause a drop in line voltage resulting in loss of power and overheating.
6. Inspect the hoist as explained in Frequent Inspection on page 8 after installation but before use.

Inspection, Testing, and Maintenance Specific Safety Information

1. Perform a “Frequent Inspection” at least monthly, see page 8.
2. Perform a “Periodic (Thorough) Inspection” at least yearly, see page 8.
3. More frequent inspections are needed for hoists that are used heavily.
4. Raise test loads only to the minimum extent needed and stay well clear of load at all times during testing.

Operation Specific Safety Information

1. Wear ANSI-approved safety goggles, ANSI-approved hard hat, and steel-toed work boots during setup and use.

Grounding Instructions

TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING WIRE CONNECTION READ AND FOLLOW THESE INSTRUCTIONS.

1. In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This hoist is equipped with an electric cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with all local codes and ordinances.
2. Do not modify the plug provided – if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
3. Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor with insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment grounding conductor to a live terminal.
4. Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in doubt as to whether the hoist is properly grounded.
5. Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the hoist’s plug.
6. Repair or replace damaged or worn cord immediately.

125 VAC 3-Prong Plug and Outlet (for up to 125 VAC and up to 20 A)

TO PREVENT SERIOUS INJURY: Operation of a vertical hoist involves more than depressing the UP or DOWN control. The use of vertical hoists is subject to certain hazards that cannot be met by mechanical means, but only by the exercise of intelligence, care, common sense, and experience in anticipating the motions that will occur as a result of operating the controls.

Before Operating Hoist

1.  Familiarize yourself with all operating controls of the hoist and with the operation(s) to be performed. Instructions include, the warnings on the hoist, and the safety and operating instructions portion of this manual.

2. WARNING! TO PREVENT SERIOUS INJURY FROM HOIST FAILURE:
   Do not use damaged equipment.
   If adjustments or repairs are necessary, or any defects are known, have the problem corrected before further use.

3. Do not operate a hoist with an out-of-order sign.

4. Only a qualified technician should perform maintenance to the hoist.

5. Do not use the wire rope as a ground for welding. Do not touch a welding electrode to the wire rope.

6. Designate a work area that is clean and well-lit. The work area must not allow access by children or pets to prevent distraction and injury.

7. Route the power cord along a safe route to reach the work area without creating a tripping hazard or exposing the power cord to possible damage. The power cord must reach the work area with enough extra length to allow free movement while working.
   Note: This winch requires a 20A dedicated circuit.

8. There must not be objects, such as utility lines, nearby that will present a hazard while working.

9. Inspect the hoist as explained in Frequent Inspection on page 8 after installation but before use.

Operating Controls

2 minutes in use followed by at least 8 minutes off

Emergency Shut-off Button: Press this Button to shut off the motor and disable the Controller. Twist this Button to allow it to pop up and enable the Controller.

Applying the Load

1. Do not wrap the hoist wire rope around the load.

2. Attach the load to the load hook securely by properly rated, suitable means, such as chains, shackles, hooks, lifting slings, etc. Load must be attached to prevent accidental disconnection.

3. Properly seat the sling or other device in the base (bowl or saddle) of the hook (see the left side diagram on Figure A). Do not allow the hook hitch to support any part of the load.

4. Do not apply the load to the point of the hook (shown in Figure A on the right side diagram).

5. Before moving the load, make sure wire rope is not kinked or twisted or that multiple part wire ropes are not twisted around each other.

6. Do not operate the hoist unless wire rope is seated properly on the drum, pulleys, or sprockets.

7. Do not operate the hoist unless the hoist unit is centered over the load.

8. Do not pick up a load in excess of the rated load appearing on the hoist or load block, except during properly authorized tests. Do not use a hoist overload limiting device to measure the maximum load to be lifted.

9. Give specific attention to load balancing and hitching or slinging to prevent load slipping.

Moving the Load

1. Do not engage in any activity which will divert the operator’s attention while operating the hoist.
2. Respond to signals from a designated person only. However, always obey a stop signal, no matter who gives it.
3. Do not lift or lower a load with the hoist until the operator and all other personnel are clear of the load.
4. Make sure the load and hoist will clear all obstacles before moving or rotating the load.
5. Inch hoists slowly into engagement with a load, but avoid unnecessarily inching and quick reversals of direction.
6. Do not lift a load more than a few inches until it is well balanced in the sling or lifting device.
7. Each time a load approaching rated capacity is handled, check hoist brake action by lifting the load just clear of supports and continuing only after verifying that the brake system is operating properly.
8. Do not lower the load below the point where less than two wraps of rope remain on each anchorage of the hoist drum, unless a lower limit device is provided, in which case no less than one wrap may remain on each anchorage of the hoist drum.
9. WARNING! Do not carry any load over any person.
10. WARNING! TO PREVENT SERIOUS INJURY: Do not carry personnel on the hook or the load.
11. Avoid swinging the load or load hook when traveling the hoist.
12. On trolley mounted hoists, avoid contact between trolleys and between trolleys and stops.
13. Do not use the upper limit device as a normal means of stopping the hoist. These are emergency devices only.

Parking the Load

1. Do not leave a suspended load unattended unless specific precautions have been instituted and are in place.
2. Position the load block above head level for storage when the hoist is not in use.
3. Exercise care when removing a sling from under a landed and blocked load.
4. Press the Emergency Shut-off Button to shut off the motor and disable the Controller.

Inspection, Testing, and Maintenance

Procedures not specifically explained in this manual must be performed only by a qualified technician.

TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION:
Remove any load, release the operating controls, and detach the power cord before performing any inspection, maintenance, or cleaning procedures.

TO PREVENT SERIOUS INJURY FROM TOOL FAILURE: Do not use damaged equipment. If abnormal noise or vibration occurs, have the problem corrected before further use.

Frequent Inspection

Perform the procedures in this section BEFORE INITIAL USE and AT LEAST MONTHLY. Inspection is needed more often for heavily used hoists.

1. Check operating mechanisms for proper operation, proper adjustment, and unusual sounds such as, but not limited to, binding noise of the wire rope and bearing squeal.

2. Check hoist upper limit device without a load on the hook at the beginning of each shift. Exercise care. Run the load block into its limit device at slow speed.

3. Frequent Braking System Inspection
   a. The braking system must automatically stop and hold up to the rated load if the operating controls are released and in the event of complete power failure.
   b. Braking systems must limit the speed of load during lowering, with or without power, to prevent uncontrolled or rapid lowering.

4. Frequent Hook Inspection Check hooks for the following problems:
   a. distortion, such as bending, twisting, or increased throat opening;
   b. wear;
   c. cracks, nicks, or gouges;
   d. latch engagement (if equipped);
   e. damaged or malfunctioning latch (if equipped);
   f. hook attachment and securing means.

5. Frequent Hoist Rope Inspection All ropes should be visually inspected by the operator or other designated person at the start of each shift. These visual observations should be concerned with discovering gross damage, such as listed below, which may be an immediate hazard:
   a. distortion of the rope such as kinking, crushing, unstranding, birdcaging, main strand displacement, or core protrusion;
   b. general corrosion;
   c. broken or cut strands;
   d. number, distribution, and type of visible broken wires:

6. in running ropes, 12 randomly distributed broken wires in one lay or four broken wires in one strand in one lay;

7. one outer wire broken at the contact point with the core of the rope which has worked its way out of the rope structure and protrudes or loops out from the rope structure. If such damage is discovered, either remove the rope from service or arrange for a qualified technician to give it a periodic (thorough) inspection.

8. Check wire rope reeving.

WARNING! TO PREVENT SERIOUS INJURY FROM HOIST FAILURE: Do not use damaged equipment. If any defect or damage is noted, have the problem corrected before further use.

Periodic (Thorough) Inspection

A qualified technician should perform the procedures in this section
AT LEAST YEARLY. Inspection is needed more often for heavily used hoists.
Remove or open access covers to allow inspection of components.

1. First, follow all Frequent Inspection procedures. Additionally:

2. Check fasteners for evidence of loosening.

3. Check load blocks, suspension housings, clevises, yokes, suspension bolts, shafts, gears, bearings, pins, rollers, and locking and clamping devices for evidence of wear, corrosion, cracks, and distortion.

4. Check hook retaining nuts or collars, and pins, welds, or rivets used to secure the retaining members for evidence of damage.

5. Check load sprockets, idler sprockets, drums, and pulleys for evidence of damage and wear.

6. Check the motor brake and load brake for evidence of wear.

7. Check electrical apparatus for evidence of pitting or deterioration of controller contacts.

8. Check supporting structure or trolley, if used, for evidence of damage.

9. Check warning label for legibility and replacement.

10.  Check end connections of wire ropes for evidence of wear, corrosion, cracks, damage, and distortion.

11. Periodic (Thorough) Hoist Rope Inspection Check entire length of rope hoist rope as follows: Inspect the individual outer wires in the strands of the rope. Keep a record of any deterioration resulting in appreciable loss of original strength, such as described below, and have a qualified technician determine whether further use of the rope would constitute a hazard:
    a. Check points listed in Frequent Hoist Rope Inspection on page 8.
    b. Check for reduction of rope diameter below nominal diameter due to loss of core support, internal or external corrosion, or wear of outside wires.
    c. Check for severely corroded or broken wires at end connections.
    d. Check for severely corroded, cracked, bent, worn, or improperly applied end connections.
    e. Inspect with special care the following sections of rapid deterioration:

12. sections in contact with saddles, equalizer pulleys, or other pulleys where rope travel is limited;

13. sections of the rope at or near terminal ends where corroded or broken wires may protrude;

14. sections subject to reverse bends;

15. sections of rope which are normally hidden during visual inspection, such as parts passing over pulleys.

16. Check function labels on pendant control(s) for legibility.

17. Check the hoist and hoist mounting for evidence of missing parts.

WARNING! TO PREVENT SERIOUS INJURY FROM HOIST FAILURE: Do not use damaged equipment. If any defect or damage is noted, have the problem corrected before further use.

Storage Inspection

1. A hoist that has been idle for a period of a month or more, but less than a year, must be inspected before being used according to the Frequent Inspection requirements.
2. A hoist that has been idle for a period of a year or more, must be inspected according to the Periodic Inspection requirements and then tested according to the procedure in the Testing section below before being used.

Maintenance

1. Repair or replacement of hoist components must be performed only by a qualified technician using only identical replacement parts with the same rating.

2. Operating mechanisms, limit switches, control systems, and brakes may require adjustment.

3. Note the following regarding specific components:
   a. Replace damaged or worn hooks. Do not repair them by welding or reshaping.
   b. Replace or repair all critical parts that are cracked, broken, bent, excessively worn, or missing.
   c. Replace missing or illegible warning labels.
   d. Replace pitted or burned electrical contacts as complete sets.
   e. Keep controller function labels on pendant control stations and master switches legible.

4. Do not repair load-sustaining members by welding. Replace them as needed.

5. Lubricate all moving parts regularly using grease.

6. After maintenance work is completed and before restoring the hoist to normal operation:
   a. reinstall guards;
   b. reactivate safety devices;
   c. remove replaced parts and loose material;
   d. remove maintenance equipment.

Testing

1. Before use, test repaired hoists and hoists that have not been used for a year or more.
2. Check all functions of the hoist, including lifting and lowering, with the hoist unloaded first.
3. After testing in the unloaded state, attach a 200 Ib load and retest to check proper load control and to check brake operation.
4. Test the trip-setting of limit devices under no-load conditions. Test first by hand, if practical, and then under slowest speed. Test with increasing speeds up to maximum speed. Check that actuating mechanisms are located so that they will trip the switches or limiting devices in sufficient time to stop motion without causing damage to any part of the hoist.
