HC-152
Adjustment
Level 2.
Parts Required: none
Hedge clipper blades are very sharp. Touching them may lead to severe personal injury. Use a
socket and extension when adjusting blade bolts or blade locknuts in order to keep hands at a safe
distance from sharp blades.
1. Tighten blade bolts until snug, then loosen blade bolts 1/2
turn.
2. Hold blade bolts from turning using 10 mm socket, and
tighten blade lock nuts with other 10 mm socket.
Locking ability of Hedge Clipper blade lock nuts will diminish
each time they are removed. Replace if turning resistance is not
felt when installing locknuts.
