ASSEMBLY OF CHAIN AND DISCS
The two discs secure the saw chain circlet between them.
For both the 8 tooth (shown) and the 4 tooth circlet.
NOTE DIRECTION OF RAKER POINT
I M P O R T A N T: If assembled in reverse to motor
direction, Merlin2
® will not cut, leaving burn marks on
the work piece.
The two discs secure the saw chain circlet between them.
Assembling and Changing Accessories: Outlined below is the procedure for
accessories to be correctly fitted to the mini grinder.
1) Use the Allen key 5 to unscrew accessories, simultaneously holding down button 1.
Turn the fastening screw counterclockwise using the Allen key until the locking
button engages.
2) The small fastening screw 4 with the Allen key head 5 fits through the silver centering
disc 3, which has a 10mm raised shoulder. Remove the centering disc and the
accessory to be replaced. Get the required new accessory, (all of which have a
10mm center hole), and fit it over this shoulder.
3) When mounting the saw chain assembly, make sure the chain is secured between the
discs and the chain is facing the right direction with the raker on the left. Another
check is to make sure that the number 25 stamped on tang of the chain is face down.
4) The bottom saw chain disc sits on (not over) the silver spacer (which is part of
the grinder).
5) Simply tighten the screw 4 clockwise with the Allen key 5 using the lock down switch
1 to hold the chain/discs or any accessory during tightening, making sure they are
centered for proper balance.
Do not overtighten! A quick on/off test will allow you to
check this visually. Readjust chain and discs as necessary. It’s ready to use.
Grinding Wheel Use: Good grinding performance can only be achieved using the cor-
rect and constant rotational speed. To achieve the best results when grinding metal (e.g.
sharpening mower blades), apply the grinding disc to the grinding surface at an angle of
between 30° and 40° and move evenly back and forth over the metal. Do not try to bend
the grinding disc into the cutting surface during cutting work.
Cutting Wheel Use: The fiberglass cutoff disc is designed to cut through metal rods and
metal. Taxidermists will love it. Do not use it for roughout work as there is a high risk of
fracture! Use the tungsten carbide or chain saw accessories for all roughout applications.
