Global Machinery Company 444B Drill User Manual


 
Battery charging
Connect the adaptor plug to the socket in the rear of the
battery (6). Plug the adaptor (7) into a 230–240V mains
power point and switch on. The red LED light near the
rear of the battery will show that charging is taking place.
The normal battery charge time is between 3–5 hours, but
an indication as to the battery being fully charged is
when the case of the battery starts to warm up. Once this
occurs, switch off the adaptor at the 230–240V mains
power point and remove the adaptor plug from the rear of
the battery. Your drill/driver is ready for use!
To keep the best life of the battery, let the battery start to
loose its power before charging, but do not let the drill
come to a standstill before charging. Do not do short
charges but make sure that the battery is fully charged
every time it is in need of charging.
Warning. Never store the battery out of the drill/driver as
the two contacts on top of the battery are exposed and
could be shorted by a metal object and cause a fire or
explosion!
Caution. Never use the drill while charging is in progress!
Using the drill
Use the forward/reverse switch to select the direction of
rotation, then pull the trigger (4) on. This trigger switch
is electronic variable speed which enables the user to vary
the speed continuously. The speed varies according to how
far the trigger switch is depressed, the further it is
depressed the faster the chuck will rotate and the lighter
it is depressed, the slower it will rotate.
To stop the drill, release the trigger switch.
Note. The drill will not work if the forward/reverse switch
is in the middle of the two position. This is a safety
feature and whenever leaving the drill it is wise to place
the switch in the centre to stop inadvertent switching on.
Chuck replacement
The chucks of reversible drills are always fixed by a screw
with a left-hand thread. The screw, which is located in the
centre of the chuck, must be loosened before the chuck
can be removed. To loosen the screw, turn it in a
clockwise direction. The chuck can now be removed by
unscrewing it anti-clockwise. If you have trouble removing
the chuck take the drill to your nearest authorised service
centre for chuck replacement.
Forward/Reverse switch (3)
This switch will allow you to change the direction of the
motor.
Drilling uses the forward mode. The reverse mode is
intended for the removal of screws.
Adjustable Torque
This drill is equipped with torque settings which are
controlled by the torque collar (2). By rotating the collar
behind the chuck, it is possible to adjust the torque.
This will allow better control when using the drill as a
screwdriver (prevents over-tightening of the screws).
Drilling metals
Always clamp sheet metal.
Support thin metal with a block of wood to avoid
distorting it.
Use a punch to mark the centre of the hole.
Use a suitable lubricant for the material you are
working on:
USE: FOR:
Oil Steel
Turpentine or paraffin Aluminium
Do not lubricate Brass, copper or cast iron
