Tool operators and maintenance personnel must always comply with the safety pre-
cautions given in this manual and on the stickers and tags attached to the tool and
hose.
These safety precautions are given for your safety. Review them carefully before
operating the tool and before performing general maintenance or repairs.
Supervising personnel should develop additional precautions relating to the specific
work area and local safety regulations. If so, place the added precautions in the
space provided on page 5.
The model DL07 Hydraulic Impact Wrench will provide safe and dependable service
if operated in accordance with the instructions given in this manual. Read and un-
derstand this manual and any stickers and tags attached to the tool and hose before
operation. Failure to do so could result in personal injury or equipment
damage.
• The operator must start in a work area without bystanders. Flying debris can cause serious injury.
• Do not operate the tool unless thoroughly trained or under the supervision of an instructor. Establish a training program
for all operators to ensure safe operation.
• Always wear safety equipment such as goggles, ear and head protection, and safety shoes at all times when operating
the tool. Use gloves and aprons when necessary.
• The operator must be familiar with all prohibited work areas such as excessive slopes and dangerous terrain conditions.
• Maintain proper footing and balance at all times.
• Do not inspect or clean the tool while the hydraulic power source is connected. Accidental engagement of the tool can
cause serious injury.
• Always connect hoses to the tool hose couplers before energizing the hydraulic power source. Be sure all hose
connections are tight and are in good condition.
• Do not operate the tool at oil temperatures above 140°F/60°C. Operation at higher temperatures can cause higher than
normal temperatures at the tool which can result in operator discomfort.
• Do not operate a damaged, improperly adjusted, or incompletely assembled drill.
• Never wear loose clothing that can get entangled in the working parts of the tool.
• Keep all parts of your body away from the rotating parts. Long hair or loose clothing can become drawn into rotating
components.
• Always use accessories that conform to the specifications given in the OPERATION section of this manual.
• Do not reverse impact wrench rotation direction by changing fluid flow direction.
• Release the trigger if the power supply has been interrupted.
• When working near electrical conductors, always assume that all conductors are energized and that insulation, clothing
and hoses can conduct electricity. Use hose labeled and certified as non-conductive.
• To avoid personal injury or equipment damage, all tool repair, maintenance and service must only be performed by au-
thorized and properly trained personnel.
• Do not carry the tool by hoses.

OPERATION
PREOPERATION PROCEDURES
CHECK POWER SOURCE
1. Using a calibrated flow meter and pressure gauge, check
that the hydraulic power source develops a flow of 4-12
gpm/15-45 lpm at 1000-2000 psi/70-140 bar.
2. Make certain that the hydraulic power source is equipped
with a relief valve set to open at 2100 psi/145 bar minimum.
CONNECT HOSES
1. Wipe all hose couplers with a clean lint-free cloth before
making connections.
2. Connet hoses from the hydraulic power suupply to the
tool quick disconnects. It is good practice to connect the
return hose first and disconnect it last to minimize or avoid
trapped pressure within the drill.
3. Observe the arrow on hose couplers to ensure that the
flow is in the proper direction. The male coupler on the
circtuit hose end is the supply (pressure) coupler.
4. Make sure the circuit PRESSURE (male quick disconect)
hose is conneced to the port at the back of the drill handle.
The circuit RETURN hose (female quick disconnect) is con-
nected to the port closest to the trigger.
5. Move the hyraulic circuit control valve to the ON position
to direct hydraulic flow to the drill.
Note:
If uncoupled hoses are left in the sun, pressure in-
crease inside the hose may result in making them dif-
ficult to connect. Whenever possible, connect the free
ends of the hoses together.
OPEN-CENTER (OC) OR CLOSED-CENTER
(CC) OPERATION
The DL07 can be configured to run on OC or CC circuits.
1. Determine the system type.
2. Remove the hex plug (81) from the spring cap.
FOR OPEN-CENTER OPERATION:
Using a 3/16 in. hex, reach through the hole in the spring
cap and turn the selector screw counter-clockwise until
meeting resistance (from the retaining ring). Turn the selec-
tor clockwise and then counter-clockwise to be sure the
selector is being stopped by the retaining ring. Do not force
the selector screw. Open-center operation is now selected.
FOR CLOSED-CENTER OPERATION:
Using a 3/16 in. hex, reach through the hole in the spring
cap and turn the selector screw fully clockwise. When the
selector screw bottoms. Closed-center operation is now
selected.
To prevent damage to the retaining ring, do not attempt
to force the selector screw counter-clockwise beyond
the point of initial resistance.
Reinstall the hex plug. Failure to install the plug may intro-
duce contaminants to the spool bore resulting in replace-
ment of the valve spool and main housing.
DRILL OPERATION
1. Observe all safety precautions.
2. Place the selected drill bit fully into the chuck. Center the
bit and tighten the chuck using the key provided. Remove
the key and store away from the drill.
3. Momentarily press the trigger to ensure that the drill bit
rotates clockwise and runs true.
4. Select a work position that gives secure footing and bal-
ance while operating the drill.
5. Press the drill against the work and squeeze the trigger.
The drilling method used is determined by the material be-
ing drilled and the size and depth requirements of the hole.
Brittle material such as rock, brick or concrete can be
drilled efficiently when the bit is caused to strike (hammer)
the hole bottom to break up the material. Without hammer-
ing, the rotating bit will only grind down and become dull.
The Stanley HD08 should be used for this application.
CAUTION

12
Ductile material such as metal or wood is drilled efficiently
when a steady down force is applied to the drill center to
cause the bit to slice chips of material from the hole bottom.
When drilling in metal, use a cutting lubricant to prolong bit
life and reduce the amount of force required to drill effec-
tively.
Large drill holes are more productively created from small
drill holes. Drill bits are incrementally selected to enlarge
the hole until the desired hole size is obtained. Each bit
selected must always be too large to thread and jam into
an existing hole; otherwise the bit may break and endanger
the operator.
COLD WEATHER OPERATION
If the wrench 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
o F/10oC (400 ssu/82 centistokes) before use.
Damage to the hydraulic system or wrench can result from
use with fluid that is too viscous or too thick.
OPERATION

13
• 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.
• Make sure the circuit PRESSURE hose (with male quick disconnect) is connected to the “IN” port.
The circuit RETURN 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 pressure rating of 2500 psi/172 bar.
• Do not exceed the rated flow (see Specifications) in this manual for correct flow rate and
model number. 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 personnel 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.
In addition to the Safety
Precautions in this manual,
observe the following for
equipment protection and
care.

TROUBLESHOOTING
If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem. When diag-
nosing faults in operation of the wrench, always check that the hydraulic power source is supplying the correct hydraulic
flow and pressure to the tool as listed in the following table. Use a flow meter known to be accurate. Check the flow with
the hydraulic fluid temperature at least 80oF/27oC.
PROBLEM CAUSE SOLUTION
Tool will not start.
Power not being supplied. Check to make certain that both hoses
are connected.
Turn hydraulic circuit control valve ON.
Defective quick disconnects. Check each quick disconnect.
Low drilling torque.
Relief valve set too low. Set relief valve at 2100 psi/145 bar.
Fluid restriction in hose or valve.
Excess flow and pressure loss.
Locate and remove restriction.
Use correct fluid.
Fluid not warmed up. Prehead system.
Hoses too long for hose ID. Use
shorter hose.
Hose ID too small for hose length. Use
larger ID hose.
Low tool speed. Fluid flow rate is too low. Check circuit flow rate.
High tool speed. Fluid flow rate is excessive. Check circuit flow rate. Add proper flow control valve or reduce the pump

TOOL DISASSEMBLY
GEAR HOUSING
1. Remove the chuck (33) from the output shaft (36) by
holding the seal nut (35) with an open end wrench and turn-
ing the chuck counter-clockwise.
2. Remove the capscrews (31) and lockwashers (32) se-
curing the gear housing (69) to the main housing assembly
(76). If the tool has a trigger guard (80), remove capscrew
(34), nut (20) and trigger guard before removing the gear
housing.
3. Remove the ring gear (27), roll pin (5) and gasket (71).
4. Remove the retaining ring (29) near the planet shafts
(23) before removing the planet shafts. Remove the seal
nut (35) by using the planet shaft holes to keep the output
shaft from turning. Pull the output shaft with attached parts
from the gear housing.
5. Remove the planet gears (26) from the output shaft.
Inspect shafts, gears and gear bore bushings (see CLEAN-
ING AND INSPECTION procedure).
6. Spin the ball bearing (28) on the output shaft. The bear-
ing should turn smoothly. To replace the bearing, support
the outer race and press down on the output shaft from the
chuck end. Do not reuse the ball bearing once it has been
removed from the output shaft.
7. Remove the output shaft seal (30) by pressing it from
the gear housing bore.
8. Check the end faces of the seal nut and output shaft for
nicks and war (see CLEANING AND INSPECTION proce-
dure).
MOTOR CAP
9. Remove the six capscrews (41) and lockwashers (3)
securing the motor cap assembly (46) to the main housing
assembly and lift off the motor cap assembly. Do not in any
way excessively force the motor cap off the main housing
assembly.
10. Remove the o-ring (9) from the motor cap.
MAIN SHAFT AND IDLER SHAFT
11. Tap on the small gear end of the main shaft (5) and
push the shaft from the main body.
12. Remove the idler gear (45) and idler shaft (47).
13. Remove the retaining ring (16) and then pick out the
seal washer (44), back-up ring (39) and o-ring (4) from the
main housing.
VALVE SPOOL
14. Unscrew the spring cap (66), pick out the spring (79)
and push the valve spool (59) out the spring cap end of the
main housing.
TRIGGER
15. Remove the trigger by first removing the capscrews (8)
and lockwashers (32) and removing the trigger and trigger
mount (78) as an assembly. Drive out the roll pin (21).
REVERSING SPOOL
16. Remove the retaining rings (67) and end caps (65).
17. Unscrew the seal caps (64) and slide the reversing
spool (68) out of the main housing. Make sure the idler
shaft has been removed prior to completing this step.

SERVICE
CLEANING AND INSPECTION
CLEANING
Clean all parts with a de-greasing solution. Blow dry with
compressed air or use lint-free cloths.
GEAR CHAMBER (MOTOR CAP)
The chamber bores and bottoms around the shaft bushings
should be polished and not rough or grooved. If the bushing
bores are yellow-bronze, replace them and investigate the
cause of wear.
The flat surfaces around the chamber and bolt holes should
be flat and free of nicks or burrs that could cause misalign-
ment or leaks.
BUSHINGS
The inside of the bushings should be gray with some
bronze showing through. If significant yellow-bronze shows,
replace the bushings. Inspect the motor shaft and idler
shaft for corresponding wear and replace as required.
GEARS
The drive and idler gears should have straight tips without
nicks, square tooth ends and have a smooth even polish
on the teeth and end faces. Replace the gear if cracks are
present.
MAIN HOUSING ASSEMBLY
The surface near the gears should show two interconnect-
ing polished circles without a step.
SHAFTS
The shaft diameter at the bearing and seal locations must
be smooth. Grooves, roughness or a reduced diameter
indicate fluid contamination or damaged bushings. Grit
particles may have been imbedded in the bushings, grind-
ing into the hardened shaft. If abnormal shaft wear as noted
above occurs (more than normal polishing), replace both
the shaft and associated bushings.
Also check the hydraulic system for excess contamination
in the fluid and for filter condition. Operating conditions may
require changing from a 25-micron filter to an oversized
10-micron filter.
TOOL REASSEMBLY
1. Lubricate and install a new o-ring (4) and back-up ring
(39) into the main housing. Install the seal back-up washer
(44) and retaining ring (16).
2. Slide the reversing spool (68) into the main housing as-
sembly. Insert the spool with the slot toward the idler shaft
hole and the narrow side of the depression in the spool
facing up toward the top of the main housing.
3. Insert the idler shaft (47) to prevent the reversing spool
from turning.
4. Lubricate and install a new wiper seal (63), o-ring (10),
back-up ring (17) and o-ring (2) into each seal cap (64).
Install each seal cap onto the main housing assembly.
5. Install each end cap (65) and secure with snap ring (67).
6. Lubricate seal area of main shaft (50) and install it into
the main housing. Install the idler gear (45) onto the idler
shaft.
7. Lubricate and install a new o-ring (9) onto the motor cap
(46). Lubricate capscrew threads (41) with an anti-seize
compound and install the motor cap with the capscrews
and lockwashers (3). Tighten bolts to 15-17 ft lbs / 20-23
Nm in a cross pattern.
Do not force parts together.
8. Lubricate and install a new o-ring (19) in the main hous-
ing and a new seal wiper (61) in the trigger mount (78).
Secure the trigger (77) to trigger mount with roll pin (21).
Install trigger assembly to main housing with capscrews (8)
and lockwashers (32).
9. Lubricate and install a new o-ring (18) on the valve
spool (59) before installing valve spool into the main hous-
ing from the spring cap end. Do not install the vavle spool
from the trigger side of the main housing as this will result
in spool seal damage. Ensure that the tab on the valve
spool nose is aligned with the slot in the trigger. Install
spring (79) behind valve spool. Using Loctite™ 242, install
the spring cap (66) to the main housing.
