Grizzly H7792 Drill User Manual


 
Model H7792/H7793/H7794/H7795 Cordless Drills -11-
Torque Settings
The clutch is designed to slip at a preset
torque to prevent damage to the tool or the
screw, and to prevent driving screws too
deep. Use lower torque settings for screw-
ing into soft materials with short screws,
and higher settings for harder materials
and longer screws. The clutch does not
slip when set in the drill position.
To adjust the torque:
1. Rotate the clutch ring shown in Figure
4 to adjust the torque. The clutch will
slip easiest in the number 1 setting;
the torque increases as the number
increases.

2. Turn the clutch ring to the drill setting to
prevent the clutch from slipping.
Note: DO NOT operate the drill with
the clutch set between the highest
number and the drill setting. The clutch
mechanism may be damaged.

Driving Screws
Use the lowest possible torque setting
when driving fasteners to prevent dam-
age to the screw, and to prevent driving
screws too deep.
To drive screws:
1. Install a screwdriver bit that matches
the screw head pattern.
2. Set the torque to an appropriate set-
ting for the workpiece and set the
direction to clockwise (forward).
3. Place the screwdriver bit into the
screw and the screw firmly against the
workpiece, start the drill slowly and
gradually increase speed, while apply-
ing pressure to drive the screw into the
workpiece.
Note: You may wish to drill a pilot hole
before driving the screw, depending on
the workpiece and screw type.
To remove screws:
1. Set the direction to counterclockwise
(reverse) and the clutch to the highest
torque setting.
2. Place the screwdriver bit into the
screw, pull the drill trigger, and push
lightly to keep the bit in the screw.
Operating this equipment has the
potential for flying debris to cause eye
injury. Always wear safety glasses or
goggles when operating equipment.
Everyday glasses or reading glass-
es only have impact resistant lenses,
they are not safety glasses. Be certain
the safety glasses you wear meet the
appropriate standards of the American
National Standards Institute (ANSI).
When the clutch is in the drill posi-
tion, the drill can twist severely,
causing a sprained wrist or pinching
your hand between the drill and a
solid object. Hold the drill with both
hands and be aware of the drill posi-
tion to prevent injury.
