OPERATION

Ensure that no obstruction prevents a clean lift
Gently raise or lower the load by pulling the hand chain through the block in the desired direction – Clockwise to lift and anti-clockwise to lower
While lifting or lowering a load, the hand chain should be pulled steadily so as to prevent it from jerking or tangling.
