Assembly

Note: The SLT-660F does not require any

assembly.

1. On the SLT-1650, attach the handle (A, Figure

1) to the frame using two hex cap screws, two

lock washers, two flat washers. Tighten with a

19mm wrench.

Note: The two pivoting casters can be locked

so that they do not rotate. Press foot lever (B,

Figure 1 for SLT-1650) down to lock. Press

foot lever (A, Figure 2 for SLT-660F) down to

lock.

2. Attach foot lever (A, Figure 3) to the lever

bracket (B, Figure 3) with one hex cap bolt,

one flat washer, one lock washer (C, Figure 3).

Tighten with a 14mm wrench.

Keep hands and feet clear of

table and scissor lift openings while

lowering load. Failure to comply may cause

serious injury!

3. Pump the foot lever several cycles so that the

table is out of your way while attaching the

cable.

Note: Place a 2” x 4” board straight up and

down between the table and frame so that the

table cannot come down on you while

attaching the cable.

4. Route the cable (A, Figure 4) into the cable nut

(B, Figure 4). Run the cable through the

lowering mechanism (C, Figure 4) and pull the

cable tight. Tighten the hex nut (D, Figure 4)

using a 14mm wrench.

Note: You may have to turn the hex socket

cap screw to line up the hole. This will allow

the cable to pass through freely.

Figure 4

Figure 1

Figure 2

Figure 3

Operation

1. The table can be raised by pumping the foot

lever.

Note: You may need to raise and lower the

table several times to work any air bubbles out

of the pump.

2. To lower the table, pull the release lever fully.

This allows the table to lower in a slow,

controllable manner.

3. Before loading, always lock the caster brake.

Folding Handle for SLT-660F

1. Lower the table.

2. Step on the rod that is located between the

lower sections of the handle.

3. Fold the handle flat across the table.

Maintenance

1. Lubricate each friction point monthly with #2

tube grease.

2. Check the movement and wear of wheels.

3. Check for oil leakage from the hydraulic

cylinder. Add hydraulic oil as needed.

4. Always store with table in lowered position

when not in use.
