rear width indication mark on the guard aligns with the
start line. (See Measuring the Cutting Width Section)
To ensure accurate cut-outs the guard can be held
with the free hand, but ensure it does not come into
contact with the blade.
2. Switch on the tool and wait for one second for the blade
to run up to speed. Next, plunge the blade into the
material slowly and gently, but firmly. Then push the tool
forwards along the line to be cut. (Never draw the tool
backwards)
3. Once the finish line has been reached, lift the tool from
the work surface before switching off. If a lot of dust has
been created, keep switched on for a few seconds extra
to allow the dust to clear from within the tool.
4. Cutting out tips:
 If the cut is to be covered, for example by a vent cover,
the corners can be overlapped to ensure that the waste
material is completely detached.
 If the cut out is to be seen, do not overlap the corners. In
this circumstance, as the cutting blade is circular, the
waste material will not be fully detached. The corners will
therefore, require finishing with a knife. If the material is
thin and the back surface unimportant, the waste
material can just be pushed out.
 Where there is access to the back surface of the material
to be cut, the cut out can be marked out with an over
cutting allowance. The cut is then made from the back
surface to ensure perfect corners on the front surface. A
table of over cutting allowances is shown in the
specifications section.
Cutting particularly Tough or Abrasive Materials
NB. Learn to use the tool by cutting wood before
attempting to cut anything tougher. When cutting
tougher material, such as metals and some plastics,
more force is required to hold the work piece and
clamping may be required.
Never cut materials that produce toxic dust or fumes
such as PTFE or asbestos.
Dust Extraction
The EXAKT DC-270 is a powerful tool capable of producing
a large amount of dust. As the tool has a fully enclosed
blade, forced dust extraction is particularly efficient. Forced
dust extraction should be used for all but small trimming
jobs.
1. A suitable industrial vacuum dust extractor or domestic
vacuum cleaner can be connected to the dust outlet
nozzle of the tool, using the dust hose adaptor.
2. Ensure that the vacuum cleaner to be used is
recommended for use with a power tool. Generally most
domestic wet and dry vacuum cleaners are suitable.
3. Forced dust extraction is particularly recommended
when a lot of cutting is being carried out as far fewer
stoppages are required for cleaning the tool and
surrounding area.
4. Forced dust extraction should always be used when
cutting hazardous materials such as hard woods, MDF
or ceramics.
5. Forced dust extraction is recommended when it is
desirable to keep the working area clean.
Using the parallel fence
The parallel fence is used to make cuts parallel to an edge.
To fit, first ensure tool is unplugged, then loosen the fence
locking knob, slide in the fence and tighten the knob at the
desired position.
DC-270 Safety Warnings –
Maintenance and Servicing
Cleaning
Regular cleaning is required for the safe operation of the
tool, as an excessive build up of dust will prevent the tool
operating correctly.
The dust extract nozzle may block and require cleaning
occasionally, especially if damp wood is being cut.
1. Unplug from mains supply and release guard. (See
Switch and Guard Lock Section)
2. Clean thoroughly with a small soft brush, like a paint
brush.
Safety Blade Retaining Washer
The blade is clamped in place using a special safety washer
that is designed to slip if the blade jams. The result is that the
motor slows down, sounds like it is labouring and the tool will
stop cutting. If this happens the operator should immediately
reduce the feed pressure until the motor sounds healthy or
remove the tool from the work piece to prevent permanent
damage. The washer is a consumable item, which should be
replaced if damaged or deformed.
NB. Never replace this washer with anything other than
an EXAKT replacement part. (See List of user-
replacable parts)
Blades
NB. Always use a sharp blade.
 If the tool does not cut as well as expected or if it
overheats the most common cause is a blunt blade.
 It is difficult to see or feel if the blade is blunt. If in
doubt use a new blade.
 Blades are consumable items.
 Always use EXAKT blades.
