NUTOOL NT-14F 5 SPEED DRILL PRESS

I'VE JUST PURCHASED THE ABOVE DRILL AND I'M HAVING TROUBLE CHANGING THE SPEED. I CAN'T FIND ANY WAY TO DE-TENSION THE DRIVE BELT.

ALSO, AS YOU LOOK AT THE DRILL FROM THE FRONT THERE'S A CHROME LEVER ON THE RIGHT HAND SIDE WHICH MOVES VERY SLIGHTLY BUT APPEARS TO DO NOTHING. DOES ANYONE KNOW WHAT THIS IS FOR ?

PLEASE HELP

MANY THANKS

Hi Mick,
I Can't find any information on the NT-14F but I have found a picture of the CH10 model here On that model it looks like there is a coarse threaded bolt pushing against the motor mounting plate to tension the belt. Yours may use the same method. If not can you post pictures of the motor mounting from both sides and above and below if possible. From that it should be possible to work out how the belt tension is adjusted.

My Warco drill has two locking screws (one each side) and a chrome handle that just moves a little, sliding the motor towards the front of the drill (to loosen). After changing the belt the chrome handle is returned to tension the belts and the locking screws tightened up. May be the same on yours (or a variation).

As per Les's comments. I have a similar drill press with a thumb screw on the hrs that lockers the motor mounting plate against a spring. I release this and the pull the motor forward. I can the. Move the belt across the pullys. Push the motor away and re tighten the screw.

Mick,

between the chrome lever and the end of the housing there should be a locking screw, may have a plastic knob, may be a socket cap or grub screw. There is another one on the opposite side of the housing in a similar position.

To change the tension undo these screws, then use the chrome lever to loosen/tighten the belt.

Hold the tension on the chrome lever while you re-tighten the nearest locking screw, this will hold it while you tighten the other.

The motor mount runs on 2 round bars inside the housing, hence the 2 locking screws.
