SAFETY
1.1. INTRODUCTION
Your Reimann & Georger Corporation Marine Products 24V DC direct power drive mounts to the winch side to lift your boat out of
the water. The exclusive right angle design minimizes the intrusion of dock space.
Your power drive is well-designed and well-built. However, like any other equipment, it can malfunction or become hazardous in the
hands of an inexperienced and/or untrained user. Therefore, read this manual and your related vertical lift manual thoroughly before
operating the power drive to provide maximum safety for all operating personnel, and to get the maximum benefit from your
equipment.
WARNING:
AN INSTALLED POWER DRIVE BECOMES AN INTEGRAL PART OF THE ASSOCIATED
VERTICAL LIFT. THEREFORE, DO NOT USE THE POWER DRIVE TO OPERATE THE LIFT
WITHOUT STUDYING BOTH THIS MANUAL AND THE VERTICAL LIFT MANUAL.
FAILURE TO DO THIS CAN LEAD TO MISUSE OF THE DRIVE AND/OR LIFT WITH
RESULTING DAMAGE AND/OR PERSONAL INJURY. CONTACT YOUR RGC MARINE
DEALER IF YOU HAVE ANY QUESTIONS.
1.2. INSTALLATION SAFETY
1. Insure that all bolts and nuts are fastened securely prior to operation.
1.3. OPERATING SAFETY
1.3.1. General
1. Before allowing anyone to operate the drive, be sure they fully understand the proper operating procedure and the use of all
controls and connections for both the drive and the lift.
2. Completely remove any user or dealer installed locking devices before operating the lift.
3. Do not operate the drive and the lift under the influence of drugs, alcohol, or medication.
4. Do not exceed the rated maximum capacity of the lift. This can damage the drive, lift and/or boat with resulting serious personal
injury.
5. Never allow anyone into the boat when suspended in the lift.
6. Never operate the drive without the cover installed over the drive assembly. Keep fingers and clothing clear of all moving parts
of the lift and direct drive.
7. Do not attempt to make any adjustments on the lift or drive during operation.
8. Disconnect and lock out the power source when not using the drive to prevent unauthorized use.
9. Never use the drive installation or any part of the lift to hang or store any auxiliary equipment such as boating hardware.
1.3.2. Safety When Raising the Boat
1. The power drive shaft must turn clockwise to raise the platform. The brake pawl on the winch must click, indicating that the
brake is operative.
2. Do not try to raise the boat beyond the maximum lifting height of the platform. This can cause lift and drive damage.
WARNING:
IF THE POWER DRIVE SHAFT TURNS COUNTERCLOCKWISE TO RAISE THE PLATFORM,
YOU HAVE REEVED THE WINCH INCORRECTLY. THE DRIVE WILL IMMEDIATELY
ENCOUNTER STRONG RESISTANCE WHICH CAN DAMAGE THE DRIVE AND/OR WINCH
AND BREAK THE CABLE.
3
1.3.3. Safety When Lowering the Boat
1. The power drive shaft must turn counter-clockwise when lowering the platform.
WARNING:
IF THE DRIVE SHAFT TURNS CLOCKWISE TO LOWER THE PLATFORM, YOU HAVE
REEVED THE WINCH INCORRECTLY. THE BRAKE PAWL WILL NOT BE EFFECTIVE
WHICH CAN CAUSE AN UNCONTROLLED SPIN-DOWN OR “FREEWHEEL” OF THE
WINCH SHAFT. IF FREEWHEELING OCCURS, NEVER TRY TO STOP IT.
2. Counter-clockwise rotation of the power drive shaft allows the self-activating brake mechanism to provide a controlled lowering
of the platform.
WARNING:
NEVER RELEASE THE BRAKE PAWL OF THE WINCH. THIS CAN TRIGGER AN
UNCONTROLLED SPIN-DOWN OR “FREEWHEEL” OF THE WINCH SHAFT.
3. Do not continue lowering the platform after the boat floats freely. Excessive slack in winch cable may cause binding.

INSTALLATION AND SETUP
3.1. PRE-INSTALLATION CHECKS
1. Ensure that the vertical lift has been properly installed as described in your lift manual.
2. Check that the winch is reeved properly. Do not install the direct drive until the winch is reeved as described in your lift manual.
3. Do not install or use the drive if it shows any signs of damage.
4. Do not weld or otherwise modify any part of the drive assembly. Such alterations may damage the drive and/or the winch and void
the associated warranties.
5. Two people will be needed to mount this drive onto the winch. The following precautions must be observed when lifting any part
of this equipment:
a. Be sure of your footing.
b. Bend your knees and lift with your legs.
c. Hold the equipment section close to your body when lifting.
WARNING:
THE DRIVE IS TOO HEAVY TO SAFELY MOUNT IT SINGLE-HANDEDLY. ATTEMPTING THIS
CAN CAUSE EQUIPMENT DAMAGE AND/OR PERSONAL INJURY.
6. Tools required for installing this drive. Two 3/4” wrenches, two 9/16” wrenches, one 1/2” wrench, one 9/32” wrench, one 3/4” deep
wall socket with ratchet, and one #2 Phillips screwdriver.
WARNING:
DO NOT REMOVE THE BRASS WASHER FROM THE WINCH INPUT SHAFT. THE SPRING
LOADED WINCH BRAKE PAWL MUST REMAIN ENGAGED DURING THE POWER DRIVE
INSTALLATION.
