Proper Use Of Tool
Your new 3/8" Reversible Drill is designed for
drilling, honing, reaming, hole sawing and wire
bushing. This drill is also used to tighten and loosen
threaded fasteners. The Jacobs® keyless chuck
provides fast and convenient change of drill bits.
Do not use the tool for any other purpose than that
specified without consulting the manufacturer or the
manufacturer's authorized supplier. To do so may
be dangerous.
Work Stations
Your Reversible Drill should only be used as a hand
operated tool. It is always recommended that the
tool is used when standing with solid footing. It can
be used in other positions but before any such use,
the operator must be in a secure position having a
firm grip and footing.
Putting Into Service
Air Supply
Use a clean lubricated air supply that will give a
measured air pressure at the tool of 90 psi/6.2 bar
when the tool is running with the trigger fully
depressed. Use recommended hose size and length.
It is recommended that the tool is connected to the
air supply as shown in figure A. Do not connect the
tool to the air line system without incorporating an
easy to reach and operate air shut off valve. The air
supply should be lubricated. It is strongly
recommended that an air filter, regulator, lubricator
(FRL) is used as shown in figure A as this will
supply clean, lubricated air at the correct pressure
to the tool. Details of such equipment can be
obtained from your supplier. If such equipment is
not used then the tool should be lubricated by
shutting off the air supply to the tool and then
depressurizing the line by pressing the trigger on
the tool. Disconnect the air line and pour into the
intake bushing a teaspoon (5 ml) of a suitable
pneumatic motor lubricating oil, preferably
incorporating a rust inhibitor. Reconnect tool to air
supply and run tool slowly for a few seconds to
allow air to circulate the oil.
Lubricate tool daily if used frequently, or when it
starts to slow or lose power.
Operating Instructions
Installation/Removal of drill bit
1.
ALWAYS disconnect drill from air supply before
changing drill bits!
2.
Hold the bottom portion of the chuck while
turning the upper portion in a counter-clockwise
direction to loosen the chuck jaws.
3.
Fully insert the drill bit into the chuck.
4.
Tighten the chuck jaws by grasping the bottom
portion while turning the upper portion in a
clockwise direction. To ensure proper operation,
ensure that the bit is entered between the
jaw teeth.
For removal, reverse steps 2-4.
Drilling
1.
Mark the desired drilling location with an awl or
punch to provide a seat for the tip of the bit.
2.
Whenever possible, secure the workpiece in a
vise or clamp prior to starting drilling.
3.
Place drill bit tip on location of mark (Step 1)
and apply pressure to trigger to start drill. (If
drilling metal, apply lubricant to reduce friction
and glazing).
4.
Apply constant, even pressure while guiding
the drill.
5.
Reduce pressure before cutting through
workpiece. Continue depressing trigger until
bit is fully removed from the drilled hole.
Use of safety glasses and a breathing mask is
recommended. Drilling certain materials may create
hazardous dust which may require special breathing
equipment. Check before using the tool. Although
the tool has a low noise level, the actual drilling
process may cause a noise level such that ear
protectors will be required. Safety gloves
are recommended.
Caution
Drill bit or surface may become extremely hot
during drilling. DO NOT touch until cooled.
Using A Reversible Drill
1)
Read all instructions before using this tool. All
operators must be fully trained in its use and
aware of these safety rules.
2)
Do not exceed the maximum working air
pressure of 90 psi/6.2 bar.
3)
Use personal safety equipment.
4)
Use only compressed air at the recommended
conditions.
5)
If the tool appears to malfunction, remove from
use immediately and arrange for service
and repair.
6)
If the tool is used with a balancer or other
support device, ensure that it is fixed securely.
7)
Always keep hands away from the working
attachment fitted to the tool.
8)
The tool is not electrically insulated. Never use
the tool if there is any chance of it coming into
contact with live electricity.
