Aero-motive Woodhead BF Series サービスマニュアル

SPRING TENSION ADJUSTMENT

Do not push tension lock lever without placing wrench onto mainshaft first. High spring

CAUTION:

torque will turn mainshaft rapidly clockwise. Hazards or unsafe practices COULD result in

minor personal injury or product or property damage.

NOTE: Do NOT over-tension balancer main spring. This will reduce cable travel and spring life.

NOTE: If drum locks up (cable will not pull out) when reducing spring tension, increase tension until

automatic lock disengages. (See Automatic Lock)

Observe following before making spring tension adjustments:



Tool and all accessories are attached to tool clip.



Tool will lower if the weight of tool exceeds tension adjustment of

balancer mainspring.



If cable stop is tight against cable guide prior to adjustment, there

is too much tension on balancer mainspring.

To increase spring tension, turn mainshaft with wrench ¼ turn (one

click at a time) in a counter-clockwise direction ( "+" symbol on case).

Repeat until desired tension is achieved. To reduce tension, turn

mainshaft with wrench in counter-clockwise direction until tension lock

lever disengages. Hold tension lock lever in disengaged position and

carefully allow mainshaft to slowly unwind clockwise.

Repeat until desired tension is achieved.

CAUTION: Reducing cable tension below balancer minimum

rating or releasing cable with no load attached may cause cable

to jam inside.

CABLE STOP ADJUSTMENT

NOTE: Moving cable stop and bumper closer to the cable guide will shorten active travel of cable.

Make all cable stop adjustments after tool and accessories have been attached to tool clip and after

adjusting spring tension. (See Spring Tension Adjustment). Loosen two hex nuts and machine screws.

Slide cable stop and bumper up or down on cable so that tool is positioned at desired working height.

Tighten loosened hardware to hold cable stop at set position.

AUTOMATIC LOCK

Never remove spring from drum and spring assembly. Replacement springs are sealed for

WARNING:

safety. Hazards or unsafe practices COULD result in severe personal injury or death.

If tension is reduced to below rated range, automatic lock will engage and prevent cable drum from

turning. Increase tension until automatic lock disengages. If a spring should break, automatic lock will

engage to prevent drum from turning. Lock will disengage after new spring assembly is installed.
