 Conventional tools such as keyhole saws or knives
generally give excellent results, though the EXAKT
Precision Saw can be used if a particularly neat, dust free
cut is required or if there is a danger of cutting pipes or
cables.
Dust Extraction
The EXAKT Precision saw 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 kit from EXAKT
Precision Tools Ltd.
2. Before using ensure that the metal retaining clip is flush
with the end of the hose.
3. To attach the hose disconnect the tool from the mains
supply. Press the hose end with the metal clip onto the
dust outlet nozzle only as far as the raised ridges on the
tool body. Ensure the guard moves up and down freely.
Press the stepped adaptor onto the vacuum hose. Tape
can be used to assist, if required.
4. 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.
5. 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.
6. Forced dust extraction should always be used when
cutting hazardous materials such as hard woods, MDF
or ceramics.
7. Forced dust extraction is recommended when it is
desirable to keep the working area clean.
8. Forced dust extraction is essential if the material being
cut is slightly damp.
Temperature cut-out
The EXAKT Precision Saw is fitted with a temperature cut-
out to prevent the tool overheating.
If the cut-out trips the tool will stop. It will not re-start until the
tool has cooled down. This could take up to 15 minutes.
The temperature cut-out will trip in the following
circumstances:
 Using blunt blades.
 Excess force applied when cutting.
 Continuous cutting of very hard or thick materials.
Using a V Guard
A V Guard can be purchased as an accessory or may be
included in the kit from some suppliers. The V Guard is used
to cut plastic, copper and aluminium pipes as well as
wooden dowel.
1. To fit the V Guard see Guard removal section.
2. For cutting copper or aluminium pipes only use a 60 or
80 tooth blade.
3. Place the pipe so that the area being cut is fully
supported on the work surface.
4. Place the saw on top of the pipe to be cut and use free
hand to rotate the pipe as required. Ensure that the hand
holding the pipe is kept at a safe distance from the
cutting blade.
EC-320 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.
5. Unplug from mains supply and remove guard. (See
Guard Removal Section)
6. Clean thoroughly with a small soft brush, like a paint
brush.
7.
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 (temperature cut out may trip) 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.
 Beware when changing blades as they can become hot
during use. Allow the blade time to cool before replacing.
