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

the Speed Dial (Figure 2 Item 2) slowly towards the MAX.

Figure 1

Note: All accessories are shown, please follow applicable instructions only

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.

the Mounting Clip (Figure 6 Item 3) is clipped to the assembly.

4. Adjust the length of legs by lifting the red Lock (Figure 6 Item 5) and sliding each leg to

the desired length. Lower the red Lock back to lock the leg in place.

Maintenance Instructions

•Ensure the cable head is properly secured during transport and storage.

•Regularly inspect the cable head o-ring condition and o-ring seal area for cleanliness.

This area should be free of debris and lubricated as needed.

•The cable head will experience normal wear during use and will need to be replaced at

various intervals depending on care and usage. A Cable Head Repair Kit, Part# 126883,

is available to replace the cable head in the field as needed. It can be purchased at

www.lavalparts.com or by calling +1 (559) 251-1396.

•Wash the Camera with fresh water and wipe clean after use. Ensure the camera is free

of unwanted oil and contaminates. If necessary, use mild dish soap to clean the camera.

•Prior to and after conducting each survey, inspect the glass ports on the side-view and

down-view for any cracks or debris in crevices. If necessary, use household glass cleaner

to clean the viewing ports.

•Inspect the cable head connection point at the top of the camera before connecting the

cable head to the camera. This area should be clean, free of debris, and the pins should

be in the upright position. If the pins are bent or deformed, do not attempt to connect

the cable head.

•When not in use store the system in an indoor, temperature-controlled environment in

the carry case and foam pads provided.

•Guide the cable evenly across the drum and wipe clean when spooling to prevent

contamination, build-up, and damage.

•Keep the Control Unit clean and free of debris. Wipe clean after each use.

•Before use check the lead screw for debris and dirt. Wipe clean as needed.
