*When winding backwards off the takeup reel, make sure to set the takeup direction to neutral and rotate the reel backwards with your hand (do NOT pull on the film to rewind it, which will cause cinch scratching). Reversing the motor direction to feed the film back for long distances is not advisable because it gives you less control, and it risk spilling film onto the floor. | *When winding backwards off the takeup reel, make sure to set the takeup direction to neutral and rotate the reel backwards with your hand (do NOT pull on the film to rewind it, which will cause cinch scratching).

*Kelmar spindles are somewhat weaker than other models. If the spindles get bent or become orbital (the tip of the spindle will wobble rather than spinning evenly on its axis) replace them. | *Kelmar spindles are somewhat weaker than other models.

*The throttle knob is connected to a carbon wiping brush that controls a variable transformer to regulate motor power. This brush can wear down, causing the motor to cut out intermittently at lower speeds. It will still operate normally at higher speeds, because the higher current can arc despite the worn brush. If the motor is cutting out at low speeds, contact a service technician for repair. | |||
