Safety Instructions for Electric Hoists 1. READ THROUGH THE ENTIRE MANUAL BEFORE USING. This electric hoist represents serious injury hazards to untrained users. 2. NEVER ALLOW UNQUALIFIED PERSONNEL TO SERVICE THIS HOIST. Servicing the hoist incorrectly may reduce the maximum holding capacity. 3. DO NOT LIFT MORE THAN THE MAXIMUM SUGGESTED CAPACITY. Be aware that the load weight, harnesses, and load bearing equipment all contribute to the total load weight. Overloading may cause the load to fall. 4.

SECTION 3: SET UP Unpacking A Your electric hoist was carefully packaged for safe shipping. If you discover any damage after you have signed for delivery, immediately call Customer Service at (570) 546-9663 for advice. B D C Save the containers and all packing materials for possible inspection by the carrier or its agent. Otherwise, filing a freight claim can be difficult. When you are completely satisfied with the condition of the shipment, you should inventory the contents.
Setup The Model H0778/H0779 electric hoist comes pre-assembled. The hoist only needs to be mounted. There are many mounting options for your hoist. It may be mounted on a stationary pipe or on a rotating pillar (Figure 3). Figure 4. Mounting the hoist (pole not shown for clarity). 3. Firmly tighten the hex bolts and check to make sure the hoist does not swing or move on the pipe. Mounting and Loading Hardware When attaching hardware to the electric hoist: Figure 3. Hoist mounted on a rotating pillar.
Test Run 3. Let go of the hook and move to a safe distance. The Model H0778/H0779 electric hoist has a safety stop microswitch that will automatically shut OFF the motor before the lift or pulley hook can be retracted into the housing. If the hook is allowed to retract into the housing, the hoist will continue to pull the cable until the cable or cable hardware breaks, causing the load to drop and resulting in possible property damage/ injury.
SECTION 4: OPERATIONS To use the electric hoist: 1. Plug the electric hoist into a grounded 110V outlet. 2. Grab the lift hook and pull it away from the hoist while using the control switch to lower the hoist cable by pressing the switch in the down position (Figure 6). Never fully unwind the cable from the electric hoist. Always leave at least 3 turns of cable on the hoist spool to prevent the cable from detaching. 3. Verify the weight of the item to be hoisted.
SECTION 5: MAINTENANCE General Lubrication Check mounting hardware daily before use for cracks, unsafe wear, deformation, or warping. DO NOT attempt to fix the mounting hardware! Discard and replace all damaged mounting hardware. Check daily for loose pins, rings, screws, wires and safety latches. Tighten or replace any loose items. Check daily for damage or fraying along the length of the cable. Damaged or loose parts may cause the load to fall and may result in serious injury.
