SAFETY SYMBOLS Safety symbols and signal words, as shown below, are used to emphasize all operator, maintenance and repair actions which, if not strictly followed, could result in a life-threatening situation, bodily injury or damage to equipment. This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.
SAFETY PRECAUTIONS Tool operators and maintenance personnel must always comply with the safety precautions given in this manual and on the stickers and tags attached to the tool and hose. To avoid serious injury or death These safety precautions are given for your safety. Review them carefully before operating the tool and before performing general maintenance or repairs.
TOOL STICKERS & TAGS HD45 HAMMER DRILL WEIGHT: 22 KG/48 LB FLOW: 34 LPM/9 GPM PRESSURE: 140 BAR/2000 PSI Stanley Hydraulic tools Division of the Stanley Works 3810 SE Naef Road Milwaukie, OR 97267 29689 Name Tag 05152 Stanley Decal 28376 Stanley Decal (CE Models) CAUTION 7-9 GPM / 26-34 LPM DO NOT EXCEED 2000 PSI / 140 BAR DO NOT EXCEED SPECIFIED FLOW OR PRESSURE USE CLOSED-CENTER TOOL ON CLOSED-CENTER SYSTEM. USE OPEN-CENTER TOOL ON OPEN-CENTER SYSTEM.
HYDRAULIC HOSE REQUIREMENTS HOSE TYPES Hydraulic hose types authorized for use with Stanley Hydraulic Tools are as follows: Certified non-conductive Wire-braided (conductive) Fabric-braided (not certified or labeled non-conductive) Hose listed above is the only hose authorized for use near electrical conductors. Hoses and listed above are conductive and must never be used near electrical conductors.
HTMA REQUIREMENTS TOOL CATEGORY HYDRAULIC SYSTEM REQUIREMENTS FLOW RATE TYPE 1 TYPE II 7-9 gpm (26-34 lpm) 2000 psi (138 bar) TYPE III TOOL OPERATING PRESSURE (at the power supply outlet) 4-6 gpm (15-23 lpm) 2000 psi (138 bar) SYSTEM RELIEF VALVE SETTING (at the power supply outlet) 2100-2250 psi 2100-2250 psi 2100-2250 psi 2200-2300 psi (145-155 bar) (145-155 bar) (145-155 bar) (152-159 bar) MAXIMUM BACK PRESSURE (at tool end of the return hose) 250 psi (17 bar) Measured at a max.
OPERATION PREOPERATION PROCEDURES CHECK POWER SOURCE 1. Using a calibrated flowmeter and pressure gauge, check that the hydraulic power source develops a flow of 7-9 gpm/26-34lpm at 1500-2000 psi/105-140 bar. 2. Make certain that the hydraulic power source is equipped with a relief valve set to open at 2250 psi/155 bar. CHECK THE TOOL 1. Make certain all tool accessories are correctly installed. Failure to install tool accessones properly can result in damage to the tool or personal injury.
OPERATION 6. If the bit binds in the hole, reverse direction of the bit rotation to assist in “backing out” the drill. 7. Keep the drill bit centered in the hole. COLD WEATHER OPERATION If the drill is to be used during cold weather, preheat the hydraulic fluid at low engine speed. When using the normally recommended fluids, fluid temperature should be at or above 50°F/10°C (400 SSU/ 82 centistokes) before use.
CHARGING THE ACCUMULATOR ACCUMULATOR TESTING PROCEDURE To check or charge the accumulator the following equipment is required: NOTE: It may be necessary to set the gauge at 650-700 psi/45-48 bar to overcome any pressure drop through the charging system. 4. Open the valve on the charging assembly hose. IMPORTANT 31254 Charge Kit: which includes the following. • Accumulator Tester (Part Number 02835). • Charging Assembly (Part Number 15304).
CHARGING THE ACCUMULATOR 13
TOOL EQUIPMENT & CARE NOTICE In addition to the Safety Precautions on page in this manual, observe the following for equipment protection and care. • Make sure all couplers are wiped clean before connection. • The hydraulic circuit control valve must be in the “OFF” position when coupling or uncoupling hydraulic tools. Failure 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.
TROUBLESHOOTING listed in the table. Use a flowmeter known to be accurate. Check the flow with the hydraulic fluid temperature at least o o 80 F / 27 C. If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem. When diagnosing faults in operation of the hammer drill, always check that the hydraulic power source is supplying the correct hydraulic flow and a pressure to the tool as PROBLEM Drill does not run. Drill does not drill effectively.

SERVICE Good maintenance practice keeps the drill on the job and increases its service life. The most important maintenance practice is to keep the hydraulic fluid clean at all times. Contaminated hydraulic fluid causes rapid wear and/or failure of internal parts. Follow the procedure contained in the HYDRAULIC SYSTEM REQUIREMENTS section of the manual to ensure peak performance from the tool. 4. Remove the two capscrews (3/8 hex socket) and two side rods.
SERVICE 5. To remove the flow sleeve from the flow sleeve tube, remove the automatic valve body and associated parts from within the flow sleeve removal tube and continue pushing on the flow sleeve until it drops out. Obtain seal kit (Part Numbe 05839) so all seals exposed during disassembly can be replaced during assembly. Ensure that all seals that were exposed have been replaced with new parts. IMPORTANT Apply clean grease or o-ring lubricant to all parts during reassembly.
SERVICE 3. Place the motor plate on an aluminum plate latch end up in an arbor press. 15. Install a white backup ring and a quad ring seal in the seal counter bore of the motor control block. 4. Install latch parts with Latch Installation Tools (part numbers 05062 and 05879) in the following order: a. Latch (in the open position) b. Latch Washer c. Four Wave Springs e. Latch Washer f. Four Additonal Wave Springs g. Spring Backup h. Assembly Guide i. Wire Retaining Ring.
SERVICE 7. Install the porting block into the end of the automatic valve body with proper roll pin alignment. 8. Place the flow sleeve assembly in a bench vise, being careful not to overtighten or distort the tube and install the accumulator valve block. Rotate the flow sleeve so that the motor roll pin alignment hole will locate the motor control valve lever under the handle on the valve lever side. 9. Slide the motor assembly over the piston.
