POWER SUPPLY
For the best performance, the machine should be connected to the Markusson
Converter. The machine can also be powered from a 12-volt car battery or from
a battery charger with an output of 12 –15 volts DC (min 10 ampere). When
using a battery, connect the red cable to the positive terminal (+) and the black
one to the negative (-).
If the cables are connected to the wrong terminals, the grinding disc and the
feeder motor will turn in wrong direction, causing the machine to break
down. Compare the direction of rotation with the arrow on the cover.

CENTRING THE GRINDING WHEEL
If the lengths of the right and left cutting links turn out different on sharpening,
this can be adjusted with adjusting screw 12. When the screw is adjusted, the
length of the inner or outer cutting links will increase/decrease.
Be prepared to stop the machine if something goes
wrong during trial sharpening.
Check the grinding disc for cracks and that it is securely fixed
to the hub. Stop the grinding wheel immediately if abnormal
vibrations occur.

COUNTER
The counter is placed above the control panel, maximum count is 999 teeth. The counter is
programmed using the three buttons to the right. To set the number of teeth, push the right
button to set XX0-XX9 (ones), the middle one to set X1X-X9X (tens) and the left one to
set 1XX-9XX (hundreds). The number of teeth will be stored in memory until the next
time the value is set.
When the machine is running, the number of teeth grinded will be counted and the
machine will stop when the preset number is reached.
To restart the machine (and to reset the counter), push the red button.
SPEED CONTROL
The speed control is placed below the counter. This control the lowering speed of the
grinding head (grinding wheel) as it grinds the tooth. High speed can be used when
grinding 0-1mm of the tooth, low speed when grinding 1-4mm.

CHAIN LOCK ADJUSTMENT, DIFFERENT CHAIN TYPES
The lock adjustment is placed to the right. This is used to change the locking point on the
chain ruler when grinding different types of chains.
To change the locking point: stop the machine when the chain is ”free”. Loosen the plastic
nut (1) and move the lever either to 404 / 3/8 / .325 (position 1) or to 3/4 (position 2).
When this is done the spacers between the rulers needs to be fitted as shown below. When
delivered the spacers are fitted for position 2. Loosen the outer chain ruler, fit spacers as
shown below and the re-fit the ruler.
NOTE!
When changing the locking point, the lever must be positioned in either
Pos –chain size 404 / 3/8 / .325 or Pos –chain size 3/4. The lever must not be
positioned in between Pos and Pos as this might cause the machine to break
down.

WIRE ADJUSTMENT
For the grinding machine to function properly, it is important that the wire is adjusted
correct. It is set in factory but will be worn over time making adjustment or replacement
necessary. To adjust the wire correct, follow these steps:
NOTE! The machine is to be set at high speed (rabbit) when adjusting the wire.
1. Start by turning the grinding 2. Set the angle to 30°.
head to the left. NOTE: Head to the left.
3. Turn the machine and have a look 4. The lifting arm (1) shall meet the
At the back. Start the machine and flange (2) app. 1,5 sec before
observe as the lifting arm (1) lifting again. Use a 0,05 mm feeler gauge
meets the flange (2). between the arm and the flange to control
that contact is made.
Pictures (step 3 & 4), see next page.

13
5. To adjust the wire, making the arm make contact with the flange longer, turn nuts
as shown below (4). To adjust for a shorter time of contact, see below (3).
4. Longer time 3. Shorter time

14
GRINDING WHEEL ADJUSTMENT DEPTH
It is possible to adjust the position of the grinding motor turning the knob on the front of
the grinding head. An arrow indicates a number on a scale. This adjustment is used as the
diameter of the grinding wheel decreases when it is worn.
When fitting a new grinding wheel, the arrow should point at 1-3 on the scale. As the
wheel is worn, it should be adjusted to a higher number making sure that each tooth is
equally deep.
STROKE ADJUSTMENT
The stroke adjustment (distance between to teeth) is done with the wing-nut on top of the
machine. Loosen the nut and position it according to the label. This must be changed if
chains with different pitch are grinded, for example 3/4 to 404. It is important the the
feeder arm stops right above the rivet behind the cutting link. Se pictures below.
NOTE: Not to be mixed up with the cutting tooth length setting.

15
GRINDING THE DEPTH GAUGE LUGS.
WHEN TURNING ON THE DEPTH GAUGE GRINDING,
ENSURE THAT THE MACHINE IS IN A MODE WHERE THE
CHAIN IS NOT LOCKED. I.E WHEN FEEDING THE CHAIN
FORWARD.
Set grinding angle to 0°, see chapter ”GRINDING ANGLE”.
CHECK THE GRINDING DISC FOR CRACKS AND THAT IT
IS SECURELY FIXED TO THE HUB.. STOP THE GRINDING
WHEEL IMMEDIATELY IF ABNORMAL VIBRATIONS
OCCUR.
Fit the appropriate disc (1), (6mm for smaller chains for ex. 404, and 10mm for 3/4-
chains). Profile the disc, giving it a profile matching the lug (2). Adjust the feeder arm (3),
until the disc (1) meets the lug (2) in correct position. (See picture below). Proceed as if
grinding the chains cutting links.

16
TRIAL SHARPENING
Test the various functions of the machine and study the motions.Always stop the machine
when the grinding head reaches itsuppermost position. The chain rulers are then
“unlocked” and thechain is free. When you have done a trial run with the machine and
feel familiar with it, you can put in a chain. Now test-sharpen a chain,
following the instructions in under Sharpening cutting links.
In the interest of safety, use an old chain.
SHARPENING CUTTING LINKS
Always use safety gloves when handling saw chains.
Risk of cutting injury.
To sharpen a chain in the Combimatic machine, proceed with these steps:
(Numbers correspond to parts shown on page 17)
1. Activate power (Power in) - 8
2. Start grinding motor - 1
3. Profile the disc –see picture below
4. Turn grinding motor off - 1
Place the chain to be sharpened between chain rulers 5.
Pull the chain around by hand and check that it runs freely in the chain rulers
Check also whether the chain has “double links”, that it does not have any burrs
on the drive links and that it is not damaged.
NOTE: If there are double links, see the instructions for double links.
