SAFETY SYMBOLS

DS12 User Manual ◄ 5
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.
These safety precautions are given for your safety. Re-
view them carefully before operating the tool and before
performing general maintenance or repairs.
Supervising personnel should develop additional pre-
cautions relating to the specic work area and local
safety regulations. If so, place the added precautions in
the space provided in this manual.
The DS12 Utility Saw will provide safe and dependable
service if operated in accordance with the instructions
given in this manual. Read and understand this manual
and any stickers and tags attached to the tool and hoses
before operation. Failure to do so could result in per-
sonal injury or equipment damage.
• Establish a training program for all operators to en-
sure safe operation.
• The operator must be familiar with all prohibited
work areas such as excessive slopes and danger-
ous terrain conditions.
• Do not operate the chain saw unless thoroughly
trained or under the supervision of an instructor.
• Always wear safety equipment such as goggles, ear,
breathing, head protection, leg protection, gloves,
snug tting clothing and safety shoes at all times
when operating the chain saw.
• Do not overreach. Maintain proper footing and bal-
ance at all times.
• Do not inspect or clean the chain saw while the hy-
draulic power source is connected. Accidental en-
gagement of the chain saw can cause serious injury.
• Always connect hoses to the chain saw hose cou-
plers before energizing the hydraulic power source.
Make sure all hose connections are tight.
• Do not operate the chain saw at uid temperatures
above 140 °F/60 °C. Operation at higher tempera-
tures can cause higher than normal temperatures
at the chain saw which can result in operator dis-
comfort.
• Do not rely exclusively upon the safety devices built
into the chain saw. As a chain saw user, several
steps must be taken to keep your cutting jobs free
from accident or injury:
a. With a basic understanding of kickbacks, you
can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.
b. Keep a good rm grip on the chain saw with
both hands, the right hand on the rear handle
and the left hand on the front handle when oper-
ating the chain saw. Use a rm grip with thumbs
and ngers encircling the chain saw handles. A
rm grip helps reduce kickbacks and maintains
control of the chain saw. Do not let go.
c. Make sure the area in which you are cutting is
free of obstructions.
d. Cut at rated operating speeds (gpm).
e. Do not overreach or cut above shoulder height.
f. Only use replacement bars and chains specied
by Stanley or the equivalent.
• Make sure the chain guard is in place before operat-
ing the chain saw.
• Remove or control the water slurry to prevent your-
self or others from slipping while cutting.
• Provide adequate ventilation in closed areas when
operating a gas or diesel hydraulic power source.
• Do not operate a hydraulic power source or a hy-
draulic diamond saw in an explosive atmosphere.
• Warning: Use of this tool on certain materials during
demolition could generate dust potentially contain-
ing a variety of hazardous substances such as as-
bestos, silica or lead. Inhalation of dust containing
these or other hazardous substances could result
in serious injury, cancer or death. Protect yourself
and those around you. Research and understand
the materials you are cutting. Follow correct safety
procedures and comply with all applicable national,
state or provisional health and safety regulations
relating to them, including, if appropriate arranging
for the safe disposal of the materials by a qualied
person.
SAFETY PRECAUTIONS

6 ► DS12 User Manual
• Always be well rested and mentally alert before op-
erating the chain saw.
• Do not allow bystanders near the chain saw when
starting or cutting.
• Do not start cutting until you have a clear work area
and secure footing.
• Keep all parts of the body away from the chain saw
during operation, including loose clothing and long
hair.
• Carry the chain saw with the tool de-energized and
the bar and chain to the rear of your body.
• Do not operate a chain saw that is damaged, im-
properly adjusted, or not completely and securely
assembled. Make sure the chain stops moving
when the control trigger is released.
• Keep the handle dry, clean and free of hydraulic
uid.
• Do not use the chain saw near energized transmis-
sion lines.
• Turn off the power source or move the hydraulic
control valve to neutral before setting the chain saw
down.
• Use a guide bar scabbard when transporting the
chain saw.
• Know the location of buried or covered utilities be-
fore starting work.
• To avoid personal injury or equipment damage, all
chain saw repair, maintenance and service must
only be performed by authorized and properly
trained personnel.
• Make sure the chain breaker and rivet spinner are
securely mounted on at, clean work surfaces.
Check the mounting screws/bolts often.
• Check all chain breaker and rivet spinner compo-
nents regularly for wear and general condition.
• Avoid contact with the saw bar rails as they can be-
come very sharp during use.
• Provide adequate lighting when operating the saw in
a darkened area or at night.
• Always keep critical tool markings, such as labels
and warning stickers legible. Always replace stick-
ers and decals that have become worn or damaged.
• Be observant of hydraulic and water hoses that lay
about the work area, especially in trenches where
they can be hidden from view due to liquids that
have accumulated within the space.
• Keep all parts of the body away from the cleats that
are attached to the saw, as these are sharp and can
be a puncture hazard.
• Improper handling, use, or maintenance can result
in an oil leak or burst. Do not contact an oil leak as
high pressure oil can cause injection into the body.
• Never stand in the path of the discharge, as ejection
of material from the work piece can cause personal
injury.
• Never use the saw in a potentially explosive atmo-
sphere.
• WARNING: Hydraulic uid under pressure could
cause skin injection injury. If you are injured by
hydraulic uid, get medical attention immedi-
ately.

The rated working pressure of the hydraulic hose must be equal to or higher than the relief valve setting on the hy-
draulic system. There are three types of hydraulic hose that meet this requirement and are authorized for use with
Stanley Hydraulic Tools. They are:
Certied non-conductive — constructed of thermoplastic or synthetic rubber inner tube, synthetic ber braid
reinforcement, and weather resistant thermoplastic or synthetic rubber cover. Hose labeled certied non-
conductive is the only hose authorized for use near electrical conductors.
Wire-braided (conductive) — constructed of synthetic rubber inner tube, single or double wire braid reinforce-
ment, and weather resistant synthetic rubber cover. This hose is conductive and must never be used near
electrical conductors.
Fabric-braided (not certied or labeled non-conductive) — constructed of thermoplastic or synthetic rubber in-
ner tube, synthetic ber braid reinforcement, and weather resistant thermoplastic or synthetic rubber cover. This
hose is not certied non-conductive and must never be used near electrical conductors.

a relief valve set to open at 2100–2250 psi/145–155
bar.
3. Make certain that the power source return pressure
does not exceed 250 psi/17 bar.
CONNECT HYDRAULIC HOSES
1. Wipe all hose couplers with a clean lint-free cloth
before making connections. If necessary, use a
light-weight penetrating oil in a spray can to clean
the hose couplers before each connection.
2. Connect the hoses from the hydraulic power source
to the chain saw ttings or quick disconnects. It is a
good practice to connect return hoes rst and dis-
connect them last to minimize or avoid trapped pres-
sure within the chain saw.
3. Observe the arrow on the couplers to ensure that
the ow is in the proper direction. The female cou-
pler on the chain saw is the inlet (pressure) coupler.
4. Move the hydraulic circuit control valve to the ON
position to operate the chain saw.
NOTE:
If uncoupled hoses are left in the sun, pressure in-
crease inside the hoses might make them difcult to
connect. Whenever possible, connect the free ends
of the hoses together.
CONNECTING TO A WATER SUPPLY
1. Using a standard garden hose, connect the DS12 to
a city or auxiliary water supply.
2. If you plan on operating the chain saw in freezing
weather, make sure you purge all the water from the
system after each use.
CHAIN TENSIONING AND BAR
ADJUSTMENT
IMPORTANT
A properly tensioned chain will optimize cutting
performance. The tensioning rule of thumb for the
utility cutting chain saw is that a properly tensioned
chain must not be bowstring tight and can be pulled
freely around the guide bar by hand easily without
binding. Caution should be used when adjusting
these chains as the bar rail can become very sharp.
Lift the chain away from the bar rail when rotating
and use extreme caution.
NOTE:
The chain on the utility saw is non-directional and
may be installed to travel either direction.
PROPER CHAIN TENSION
Check the chain tension often during operation, espe-
cially during the rst 1/2 hour when using a new chain.
Adjust the chain accordingly when it becomes loose.
If the chain is too loose, it could come off the bar, or it will
allow the drive sprocket to spin without turning the chain,
which can chew up the chain drive links. If the chain is
too tight, a lot of the saw’s power goes into turning the
chain rather than into the cut. In extreme over-tightened
cases, the saw may not be able to turn the chain at all.
In addition, damage can occur to the bar nose and pre-
mature stretch may occur.
Figure 2. Proper Chain Tension
HOW TO CHECK
Before cutting, check for proper tension by pulling the
chain around the bar by hand. If you cannot easily pull
by hand, the chain is too tight and needs to be loosened.
OPERATION

12 ► DS12 User Manual
NOTE:
Make sure the bar attaching nuts are fully tightened
and the chain guard is in place.
HOW TO PREVENT CHAIN TENSIONER
BREAKAGE
Do not attempt to adjust the tensioner without rst loos-
ening the side cover nuts. Do not use the saw without
making sure the side cover nuts are tight. If the side cov-
er nuts are not tight, the bar can slip backwards during
cutting and break the tensioner pin.
ADDITIONAL INFORMATION
Utility chain saws operate with looser chain tension than
wood chain saws. It is common, on the utility chain saw
to have the drive links hang completely out of the bar.
Wood cutting chain saws use oil to lubricate the chain.
The oil makes the chain very slippery and allows the
drive links to fully nest between the teeth of the drive
sprocket. The utility cutting chain saws require water for
cooling and ushing the cut. Water is not as good as oil
as a lubricant. Also, there are cutting particles mixed in
with the water. As a result, sometimes the drive links do
not nest properly on the drive sprocket. When this hap-
pens, the chain acts like it got tighter. There seems to
be “tight” spots and “loose” spots as you pull the chain
around the bar. If you tension when the chain is in one
of the loose spots, it will be too tight at some point in it’s
rotation around the bar. Rotating the chain completely
around the bar by hand will let you know you have the
chain properly tensioned.
Figure 6. Checking for Proper Tension
ADDITIONAL TENSIONING TIPS
1. To reduce chain stretch and tensioning downtime,
use 20 PSI (1.5 bar) or greater water pressure.
2. Oil the chain at the end of the day to prevent rust but
be careful not to over tension in this condition.
Figure 3. Maximum Chain Clearance
WHEN TO TENSION
All chains have a tendency to stretch when used. Dia-
mond chains stretch more than wood cutting chains be-
cause of the abrasive materials they are cutting. When
a chain stretches to a point where the drive links are
hanging approximately 1/2 in–3/4 in (12–18 mm) below
the bar, it’s time to tension the chain.
Figure 4. When to Tension
HOW TO TENSION
To tension the chain, rst loosen the side cover nuts,
then while holding the nose of the bar up, use a screw
driver to turn the tensioning screw clockwise until the
chain drive links hanging below the bar are just begin-
ning to enter the bar groove. Continue to hold up on the
nose of the bar and rmly tighten the side cover nuts,
(20 ft-lbs, 27 Nm). And remember, it’s the side cover
nuts that hold the bar in position.

OPERATION

DS12 User Manual ◄ 13
3. When pulling the chain around the bar by hand, be
careful not to touch the bar with thumb or foren-
ger. The bar rails can be very sharp. Using leather
gloves grab only the diamond segments to pull the
chain.
4. Always turn the hydraulic power source off before
tensioning the chain.
CHECK THE WATER SUPPLY
1.
IMPORTANT
Chain and bar damage will occur if the chain saw
operates without the proper water supply.
Always have water running before starting the chain
saw.
2. Recommended water ow 4 gpm/15 lpm at 50
psi/3.5 bar (2 gpm/7.5 lpm at 20 psi/1.3 bar mini-
mum).
PRE-CUT CHECKLIST
• If using the clamp make sure it is securely fastened
before attaching the saw, tighten clamp nut with
wrench.
• Proper Chain tension: Bottom tip of drive link hangs
even with bottom of bar.
• Ensure proper water ow and hydraulic supply to
power unit.
• Ensure cut can be made clear of dirt contact.
• Protective clothing/protection in place.
• Mark cut on pipe.
• Block pipe from shifting, support weight of pipe.
WARNING
Before cutting make sure the material being cut is
properly supported from falling or shifting.
OPERATING PROCEDURES
NEW SAW CHAIN BREAK-IN
1. Always make sure the bar and sprocket are in good
condition.
2. Turn on the water supply.
3. Operate the chain saw for two minutes (away from
the intended cut) and then check the chain tension.
4. Adjust accordingly using the procedures contained
in Chain Tensioning and Bar Adjustments section of
this manual.
CUTTING TIPS
If using pipe clamp (Applicable for 4"–12", recommend-
ed for 8"–12").
• Place clamp around top of pipe, hand tighten adjust-
ment nut.
• Position saw on pipe for top down or bottom up (rec-
ommended) cut and slide saw clamp mount through
receiver hole at top of clamp, secure with snap pin.
• Slide clamp/saw assembly around pipe to optimum
cutting position and tighten clamp nut with wrench.
• Ensure saw is positioned to allow handle to pivot
during cut unobstructed, and ensure saw tip doesn’t
contact dirt.
CAUTION
When the saw cut is complete be watchful of sharp
edges around the material that has been cut.
CUTTING FREE-HAND OR WITH PIPE
CLAMP
•
WARNING
When exiting the cut, avoid applying high feed loads
as unexpected movement of the saw may result.
Using both hands, maintain rm control of the tool
throughout the entire cut.
Position saw to avoid pinching the bar or chain as
pipe is cut, support pipe from top and side to prevent
cut pipe from injuring operator.
• Hold saw so chain isn’t in contact with pipe, start
water and activate saw to recommended ow rate,
press chain against pipe slowly, apply pressure to
cut through pipe.
• Pressure can be applied to cut until saw starts to
lug, if need be back off on the cutting pressure to
maintain a good cutting speed.
• If cut in a 12" pipe exceeds 5 minutes, cut pulls to
one side, or diamond coating is gone, chain may
need replacement.
OPERATION

14 ► DS12 User Manual
Figure 7. Top down Cut
Figure 8. Bottom up Cut
PLAN THE CUT
1. Plan your cuts to prevent injury to yourself and to
keep from pinching the saw bar and chain as a result of
falling pieces of iron pipe.
2. Outline the material being cut with a permanent mark-
er for a visual guide (especially when cutting free hand).
3. Know what kind of material you are cutting.
TYPES OF CUTS
The DS12 can be operated not only using the pipe clamp
but also make free-hand cuts, any size pipe can be cut
free hand.
UTILITY CHAIN SAW CUTS
• Ductile Iron Pipe • Roong Shingles
• Insituform Pipe Lining • CMU Concrete Block
• PVC Pipe • Non Reinforced Concrete
• Copper Pipe • Roong Tile
• Steel Roong Material • Lumber
• HDPE Pipe • Masonry
1. When using the pipe clamp with a 15-inch bar the
cut capacity is 4" to 10".
2. When using the pipe clamp with a 18-inch bar the
cut capacity is 4" to 12".
3. Do not use a cutting force in excess of 45 lbs/20
kg. Excessive force causes the chain to slow down
or stall and causes premature wear of the saw bar
and chain.
4. Always maintain a high chain speed. High chain
speeds produce the best results.
5. Avoid aggressive/heavy forces. Aggressive force
can causes premature bar and chain wear.
COLD WEATHER OPERATION
If the saw is to be used during cold weather, preheat the
hydraulic uid at low power source speed. When using
the normally recommended uids, uid should be at or
above 50 °F/10 °C (400 ssu/82 centistokes) before use.
Damage to the hydraulic system or chain saw can result
from use with uid that is too viscous or thick.

GENERAL MAINTENANCE TIPS
Several simple maintenance tasks which, if performed,
can keep a chain saw operating at a high level
of efciency. Routine maintenance also keeps
replacement costs down on the parts of the chain saw,
which occasionally wear out.
If any chain saw disassembly is required, refer to the
Service Manual.
SAW BAR RAIL
A quick check can be made to determine if saw bar rail
or chain segment wear exists. Figure 7 shows a worn
saw bar rail.
Figure 7. Rail Wear
If the saw bar rails are worn, use a at le and dress
each one until it is at and square with the side of the
saw bar (Figure 7).
Also make sure the saw bar is perfectly straight. If bows
or bends are present in the saw bar, it must be replaced
before dressing any rail.
ROTATING THE SAW BAR
Maximum saw bar life can be achieved by occasionally
turning the bar over so the top and bottom bar surfaces
wear evenly. Refer to the saw bar disassembly proce-
dures in the Service Manual for further details.

• Make sure all couplers are wiped clean before con-
nection.
• The hydraulic circuit control valve must be in the
OFF position when coupling or uncoupling hydrau-
lic tools. Failure to do so may result in damage to
the quick couplers and cause overheating of the hy-
draulic 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 cir-
cuit 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 mini-
mum working pressure rating of 2500 psi/172 bar.
• Do not exceed the rated ow (see Specications)
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 in-
stalled in the pressure side of the system.
• Do not use the tool for applications for which it was not
intended.
• Oil the chain at the end of the day to prevent rust but be
careful not to over tension in this condition.
