Big switch trigger

A new big switch trigger is adopted for easier switch operation. The switch trigger is rounded for better feel
of triggering.
Soft protect cover on gear cover and inner cover
3
A transparent protect cover made of elastomer is added to cover the surfaces of the gear cover and the
inner cover made of aluminum. It is easily detachable just by removing the locator. The protect cover has
the following two features.
The material of the protect cover has extremely lower thermal conductivity than aluminum. Therefore,
the protect cover lessens feeling of coldness or hotness even if the gear cover is touched with bare
hands under the severe temperature environment such as in the severely cold areas (Russia, Eastern
Europe and Northern Europe) or the severely hot areas (Middle East and South-East Asia).
The protect cover is soft because it is made of elastomer. In addition, the aluminum gear cover protects
from damages even if the Models W 6VM, W 6V4 and W 6VA4 are hit against wall materials.

One motion detachable locator

The locator is used for adjusting the screw head depth. The current Models W 6V3 and W 6VA3 require
the operator to pull the lock sleeve and turn the locator for adjustment. The Models W 6VM, W 6V4 and
W 6VA4 are easier to adjust just by turning the locator.
Turn the locator.
