6. Adjustment of guide cover
Improper guide cover play can affect screw feeding or screw driving. Any time the VISROPE was replaced,
make sure to check the guide cover play and adjust it to the adequate level.
To adjust the play, first loosen the hexagon nut using the 7mm spanner and then adjust the cap screw using the
3mm wrench. After this, tighten the hexagon nut using the 7mm spanner to fix the cap screw.
Driving screws
1. Adjustment of rod handle length 2. Adjustment of screw driving depth
3. Direction of bit rotation
Direction of bit rotation can be reversed using the motor forward/reverse rotation switch. Use the forward
(clockwise) rotation to drive (tighten) the screw, and the reverse (counterclockwise) rotation to loosen (remove) the
screw.
Refer to the relative instruction manual of the motor on how to operate the forward/reverse rotation switch.
4. Driving screws
First, depress the lock button while pulling the trigger of the motor in order to keep the motor running. Next, hold
the handle bar of VL71-FLR and press the tool against the material at the right angle to drive the screw. When
the screw has been driven completely to the preset depth, the clutch sound can be heard. Then, reduce the
pressing force and pull back the handle bar. The screw driving is now finished and the next screw is made ready
at the same time.
* When the screw driving is finished, the sound and vibrations due to clutch contact will be produced. Go on
using the tool if there is no problem in screw driving.
* After performing several dozens of VISROPE driving, an empty plastic strip comes out long. Although the
machine is usable even if this strip is untreated, cut it with a nipper at a suitable interval lest it should be entangled
with the screws outside the magazine and should disturb the operation.
To adjust the rod handle length, loosen the knob
and press it with force to disengage the inside
fixing tab. After this, adjust the length and
tighten the knob to fix.
Turn the dial to adjust the screw driving depth.
