Hoist handle (for LT5-4/LT5-6)
The hoist handle is used to hoist up the float when you are not measuring the surface
level. This helps to add life to LT when utilized for tanks with a stirrer and/or for tanks
containing corrosive liquid.
• Do not release your grip on hoist handle when hoisting or lowering the float.
Letting go of the hoist handle may cause the float to fall and damage LT. If you
must let go of the handle during the operation, lock the hoist handle.
• Do not tilt the hoist handle more than 90 ° towards the shaft. This may cause
damage to the float, measuring tape, or conster.
Hoisting and lowering procedure
1. Remove the lock chain.
2. Move the handle slightly in the circumferential direction and gradually rotate it 180 °
towards the shaft.
When doing so, the tape drum gear and the hoist shaft gear will begin to mesh at
approximately 90 °.
3. Once the handle has been rotated to position B, rotate the handle counterclockwise
to hoist the float.
4. After hoisting the float, do not let go of the handle; be sure to secure it with the lock
chain first (see C).
Remove the lock chain when lowering the float.
5. Rotate the handle clockwise to lower the float.
When the float reaches the liquid surface, the indicator or counter will stop at the
current liquid level.
6. Once the float has been lowered, rotate the handle 180 ° towards the shaft to enable
measurements.
7. To maintain the measurement mode, wrap the lock chain once or twice around the
handle and place the hook on the end on a ring near the screw.
This completes the hoisting and lowering of the float.
