HD01 User Manual ◄ 13
Tighten further by applying the chuck key successively to all
three guide holes of the chuck.
The chuck key must not be attached to the tool with a chain,
cord, or similar means.
When drilling into small work pieces, secure the piece (by
clamping in a vise or otherwise securing it to the work sur-
face) so that the piece is not turned by the drill bit during
drilling.
IMPORTANT
When drilling into a structure that might contain
electrical wiring, be sure to know the location of the
wiring and avoid drilling into it. The housing can
carry electrical current from live electrical wires into
which the drill is accidently drilled resulting in injury
or death.
HAMMER DRILLING (PERCUSSION)
Press the hammer drill bit against the work surface before
squeezing the trigger. Do not operate the drill before con-
tacting the work surface.
When hammer drilling, do not exert heavy pressure on the
tool. Applying heavy pressure does not increase the drilling
speed. You need only press lightly. When the drill is with-
drawn from the work surface, the percussion action of the
hammer drill stops.
CHISELLING
Use the Bull-point Chisel Bit for light-duty chiselling work.
Press the hammer drill chisel bit against the work surface
before squeezing the trigger. As with hammer drilling, do not
exert heavy pressure on the tool. Press lightly.
Bull-point chisels that become blunt can be sharp ened on a
grinding machine.
LUBRICATION
Your tool was properly lubricated before leaving the factory.
In two to six months, depending on use, take or send your
tool to an authorized service center for a complete cleaning,
inspection and lubrication. Tools used constantly on produc-
tion jobs will need relubrication more often. Also tools “out of
service” for long periods should be relubricated before being
put back to work.
COLD WEATHER OPERATION
If the drill is to be used during cold weather, preheat the
hydraulic uid at low engine speed. When using the nor-
mally recommended uids, uid tempera ture should be at
or above 50 °F/10 °C (400 SSU/ 82 centistokes) before use.
Damage to the hydraulic system or drill can result from use
with uid that is too viscous or too thick.
• Make sure all couplers are wiped clean before connec-
tion
• The hydraulic circuit control valve must be in the OFF
position when coupling or uncoupling hydraulic tools. Fail-
ure to do so may result in damage to the quick couplers
and cause overheating of the hydraulic system.
• Always store the tool in a clean dry space, safe from
damage or pilferage.
• Make sure the circuit PRESSURE hose (with male quick
disconnect) is connected to the IN port. The circuit RE-
TURN hose (with female quick disconnect) is connected
to the opposite port. Do not reverse circuit ow. This can
cause damage to internal seals.
• Always replace hoses, couplings and other parts with
replacement parts recommended by Stanley Hydraulic
Tools. Supply hoses must have a minimum working pres-
sure rating of 2500 psi/172 bar.
• Do not exceed the rated ow. Refer to the Specications
page in this manual for correct ow rate and model num-
ber. Rapid failure of the internal seals may result.
• Always keep critical tool markings, such as warning
stickers and tags legible.
• Tool repair should be performed by experienced person-
nel only.
• Make certain that the recommended relief valves are
installed in the pressure side of the system.
• Do not use the tool for applications for which it was not
intended.
