anything else that may influence your vision, reaction or judgement

• Never leave the Cut-off Saw connected with the power source turned on

• Avoid lifting a higher weight than that allowed according to your local environmental work-

ing regulations

• Regular maintenance is prerequisite for machine safety. Carefully follow the operating

instructions. Replace damaged and worn components in good time. For major service to

the Cut-off Saw, contact your nearest authorized workshop. When cleaning mechanical

parts with solvent, make sure to comply with current health and safety regulations and

ensure sufficient ventilation

The Atlas Copco LS 14 Cut-off Saw and the LS 16 Cut-off Saw are sturdy and reliable saws
designed for working together with Atlas Copco power packs.

The Cut-off Saw is available in both a 14” and a 16” version. The saws are designed for cut­ting in all directions with discs both for dry and water flushed cutting. An aspirator can be con­nected to the flange socket of the guard.

The Atlas Copco LS 14 Cut-off Saw and the LS 16 Cut-off Saw are delivered with 2 m 3/8”
tail-hoses with ½” Flat-Face quick-release couplings.

The direct driven hydraulically powered design provides consistent speed and torque. It also
enables underwater cutting.

5 English

For precise and clean cutting jobs on roads, sidewalks and floors, the Atlas Copco LSC Cart
for the Cut-off Saw is recommended. The use of the Cart gives a better working posture, and
the cutting depth can be adjusted by means of an arm at the front of the Cart. The Cart is
equipped with water kit. The Cart is not standard equipment.

A separate water kit with pressure tank is also available (see the spare parts list).

The following checks should be made
eachtimeyoustarttousetheCut-offSaw.
All these checks concern the serviceability
of the Cut-off Saw. Some concern your
safety.

1. Check that the disc is in a good con­dition and properly attached

2. Clean all safety decals. Replace any
that are missing or cannot be read

3. Inspect the hoses generally for signs
of damage

4. Check for fluid leakages

5. Ensure that the hydraulic couplings
are clean and fully serviceable

6. Ensure that any power source you
plan to use is compatible with the
model of the Cut-off Saw you are
using. See the section Technical
data. Atlas Copco recommends us­ing an oil flow divider, if the flow
from the power source can exceed
the maximum allowed oil flow (see
the spare parts list)

10. Activate the water supply or aspira­tor if used

11. Place the Cut-off Saw at a right
angle on the surface to be cut and
activate the trigger lever

6WRSSLQJWKH&XWRII6DZ

1. Release the trigger. Keep a firm grip
on the Cut-off Saw, until the disc has
come to a complete stop

WARNING

The inertia of the disc is very high.
The Cut-off Saw could move and
thereby injure persons or equip­ment if placed on the ground before
thedischascometoacomplete
stop.

2. Stop the power source

3. Disconnect the hoses and fit the
protective caps to the quick-release
couplings

WARNING

Do not exceed the maximum flow
for the Cut-off Saw as this might
lead to failure of the disc and
damage of the tool.

7. Connect the hoses

8. Mount the Cut-off Saw in the Cart (if
a Cart is used)

9. Start the power source

A poorly maintained Cut-off Saw is a haz­ard. Doing regular maintenance and lubri­cation jobs as listed in these schedules will
help keep the Cut-off Saw in a safe work­ing condition.

Apart from the daily jobs, the schedules
are based on the operation hours of the
Cut-off Saw. Keep a regular check of
hours in use. Do not use a Cut-off Saw
that is due for regular service. Rectify any
defects found during regular maintenance
before clearing the Cut-off Saw for use

WARNING

Maintenance must be done only by
suitably qualified and competent
persons.

Before doing any maintenance,
make sure that the Cut-off Saw is
safe and correctly sited on level
ground.

Every 3 months

1. Do the daily jobs

2. Check tightness of nuts, bolts,
screws and hose fittings

Every 300 hours or every year

1. Do the daily jobs and jobs every 3
months

2. Check the moving parts, disc, seals
and bolts for wear and cracks.
Replace if necessary

3. Check the function of the Cut-off
Saw

6FUDSSLQJDQGZDVWHGLVSRVDO

Used and worn out parts must be treated
and disposed of in such a way that the
greatest possible part of them can be re­cycled and the influence on the environ­ment kept as low as possible.

Daily

1. Clean the Cut-off Saw in general

2. Check hoses and fittings for cracks
or leaks. Replace if necessary

3. Check for damages

WARNING

Fine jets of hydraulic oil at high
pressure can penetrate the skin. Do
not use your finge rs to check for
hydraulic oil leaks. Do not put your
face close to suspected leaks. Hold
a piece of cardboard close to sus­pected leaks and then inspect the
cardboard for signs of hydraulic oil.
If hydraulic oil penetrates your skin,
get medical help quickly.

Note: Check tightness of nuts, bolts,

screws and hose fittings after the
first days of operation and thereafter
in accordance with the maintenance
schedule
