OPERATION
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.
COLD WEATHER OPERATION
If the drill is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the nor- mally recommended fluids, fluid temperature 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 fluid that is too viscous or too thick.
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
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.
TOOL PROTECTION & CARE
NOTICE
In addition to the Safety Precautions found in this manual, observe the following for equipment protection and care.
•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 flow. 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 flow. Refer to the Specifications page in this manual for correct flow 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.
