It is not necessary to adjust the tightness of the flat

accessories-drive belt (A). The belt gets stretched

automatically.

NM14D002

If V-belt tightness (B) is appropriate, the belt sagging must

be 5.5 mm while a force of 50 N is acting on the belt.

Stretch tight the V-belt according to the prescribed value

after having loosened the fixing bolts on the air-conditioner

compressor.

NM14D003

If V-belt tightness (C) is appropriate, the belt sagging must

be 5.5 mm while a force of 50 N is acting on the belt.
