Operating Checklist
Before Starting Setup
1. Unpack the Winch (Figure 1 Item 1) and place the Winch on a stable surface, or bolt
the frame to a secure platform using appropriately rated anchors.
2. Place Control Unit (Figure 1 Item 2) within 2 feet of the Winch on a flat secure
surface.
3. Make sure the power is off by flipping the Power Switch (Figure 2 Item 6), located on
the Winch Motor Controller (Figure 1 Item 3), to the OFF position.
4. Connect the Control Cable (Figure 1 Item 4) from the Control Unit (Figure 5 Item 2)
to the Winch Control Connector (Figure 2 Item 3).
5. Connect the Power Cable (Figure 1 Item 5) from the Control Unit 12 VDC input
(Figure 5 Item 1) to the 12 VDC output on the Winch (Figure 2 Item 4).
6. Insert the Power Cord into the Power Plug on the Winch (Figure 2 Item 5).
7. Turn the Speed Dial (Figure 2 Item 2) all the way to MIN.
8. Set up your Tripod (Figure 1 Item 6) or E-Z Over (not shown) on or over the hole for
surveying.
9. Flip the Power Switch on the Winch to the ON position (Figure 2 Item 6).
10. Flip the Winch Control Switch (Figure 2 Item 1) to the FORWARD position and turn

Connecting the Camera
1. Position the Winch Power Switch to OFF (Figure 2 Item 6).
2. Before connecting the Camera to the Cable head Connector (Figure 3 Item 1) inspect the
O-rings in both connectors to be sure they are clear of debris or any contamination. Also
check for any wear or damage. The O-rings should also be re-lubricated on a regular
basis. Use a NEMA-rated O-rings lubricant.
3. Slide the Centering Band Assy (Figure 4 Item 1) and Upper Support Tube (Figure 4 Item
2) beveled end first, over and past the Cable head (Figure 3 Item 1). Connect the Twist
Locking Cable head Connector to the Camera by carefully aligning the keyway on the
connectors together and twisting the lock until seated. The cable head connector
should only be hand tightened. Never over tighten the connectors or upper support
tube.
4. Thread the Upper Support Tube to the top of the Camera. Position the Lower Centering
Band Collar on the Camera Housing (Figure 4 Item 3) at least ½” above the Side View
Port (Figure 4 Item 4) DO NOT ATTACH THE CENTERING BAND COLLAR TO WITHIN ½”
OF THE GLASS PORT. Position the Upper Collar on the Upper Support Tube so that the
Centering Bands are extended to approximately ½ inch less than the diameter of the
well or borehole being inspected.
