mendations
The chart to the right shows recommended mini-
mum hose diameters for various hose lengths
based on gallons per minute (gpm)/liters per min-
ute (lpm). These recommendations are intended
to keep return line pressure (back pressure) to a
minimum acceptable level to ensure maximum tool
performance.
This chart is intended to be used for hydraulic tool
applications only based on Stanley Hydraulic Tools

ments over a wide range of operating temperatures.
*SSU = Saybolt Seconds Universal
NOTE:
These are general hydraulic system requirements. See tool Specifi cation page for tool specifi c requirements.
1. Using a calibrated fl ow meter and pressure gauge, check
that the hydraulic power source develops a fl ow 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 fi rst and disconnect it last to minimize or avoid
trapped pressure within the drill.
3. Observe the arrow on hose couplers to ensure that the
fl ow 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 connected to the port closest to the trigger.
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.
CAUTION
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 introduce contaminants to the spool bore resulting in replacement 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.
5. Move the hyraulic circuit control valve to the ON position
to direct hydraulic fl ow to the drill.
Note:
If uncoupled hoses are left in the sun, pressure increase inside the hose may result in making them diffi cult to connect. Whenever possible, connect the free
ends of the hoses together.
OPEN-CENTER (OC) OR CLOSED-CENTER
(CC) OPERATION
The DL07 can be confi gured 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-
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 balance 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 effi ciently when the bit is caused to strike (hammer)
the hole bottom to break up the material. Without hammering, the rotating bit will only grind down and become dull.
The Stanley HD08 should be used for this application.
11
Page 12
OPERATION
Ductile material such as metal or wood is drilled effi ciently
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 effectively.
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 fl uid at low engine speed. When using the nor-
mally recommended fl uids, fl uid temperature should be at
or above 50 o F/10o C (400 ssu/82 centistokes) before use.
Damage to the hydraulic system or wrench can result from
use with fl uid that is too viscous or too thick.

EQUIPMENT PROTECTION & CARE
NOTICE
In addition to the Safety
Precautions 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.
• 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 fl 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 pressure rating of 2500 psi/172 bar.
• Do not exceed the rated fl ow (see Specifi cations) in this manual for correct fl ow 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.

TROUBLESHOOTING
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 wrench, always check that the hydraulic power source is supplying the correct hydraulic
fl ow and pressure to the tool as listed in the following table. Use a fl ow meter known to be accurate. Check the fl ow with
the hydraulic fl uid temperature at least 80o F/27o C.

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 fl at surfaces around the chamber and bolt holes should
be fl at 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 signifi cant 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.
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 assembly. 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.

(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.
CAUTION
MAIN HOUSING ASSEMBLY
The surface near the gears should show two interconnecting 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 fl uid contamination or damaged bushings. Grit
particles may have been imbedded in the bushings, grinding 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 fl uid and for fi lter condition. Operating conditions may
require changing from a 25-micron fi lter to an oversized
10-micron fi lter.
Do not force parts together.
8. Lubricate and install a new o-ring (19) in the main housing and a new seal wiper (61) in the trigger mount (78).
Secure the trigger (77) to trigger mount with roll pin (21).
