Operation; Maintenance; Optional Accessories - Makita 3620 Instruction Manual

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing the bit (Fig. 7)
CAUTION:
• Install the bit securely. Always use only the wrenches
provided with the tool. A loose or overtightened bit can
be dangerous.
• Do not tighten the collet nut without inserting a bit. It
can lead to breakage of the collet cone.
Insert the bit all the way into the collet cone and tighten
the collet nut securely with the two wrenches.
A 6 mm or 1/4" collet cone is also provided as standard
equipment besides the 8 mm or 3/8" collet cone that is
factory installed on the tool. Use the correct size collet
cone for the bit which you intend to use.
To remove the bit, follow the installation procedure in
reverse.

OPERATION

Set the tool base on the workpiece to be cut without the
bit making any contact. Then turn the tool on and wait until
the bit attains full speed. Lower the tool body and move
the tool forward over the workpiece surface, keeping the
tool base flush and advancing smoothly until the cutting is
complete.
When doing edge cutting, the workpiece surface should
be on the left side of the bit in the feed direction. (Fig. 8)
NOTE:
• Moving the tool forward too fast may cause a poor
quality of cut, or damage to the bit or motor. Moving the
tool forward too slowly may burn and mar the cut. The
proper feed rate will depend on the bit size, the kind of
workpiece and depth of cut. Before beginning the cut
on the actual workpiece, it is advisable to make a
sample cut on a piece of scrap lumber. This will show
exactly how the cut will look as well as enable you to
check dimensions.
• When using the straight guide, be sure to install it on
the right side in the feed direction. This will help to keep
it flush with the side of the workpiece. (Fig. 9)
Straight guide (Fig. 10)
The straight guide is effectively used for straight cuts
when chamfering or grooving.
To install the straight guide, insert the guide bars into the
holes in the tool base. Adjust the distance between the bit
and the straight guide. At the desired distance, tighten the
wing bolts to secure the straight guide in place. (Fig. 11)
When cutting, move the tool with the straight guide flush
with the side of the workpiece.
If the distance (A) between the side of the workpiece and
the cutting position is too wide for the straight guide, or if
the side of the workpiece is not straight, the straight guide
cannot be used. In this case, firmly clamp a straight board
to the workpiece and use it as a guide against the router
base. Feed the tool in the direction of the arrow. (Fig. 12)

Templet guide (Accessory) (Fig. 13)
The templet guide provides a sleeve through which the bit
passes, allowing use of the tool with templet patterns.
To install the templet guide, loosen the screws on the tool
base, insert the templet guide and then tighten the
screws. (Fig. 14)
Secure the templet to the workpiece. Place the tool on the
templet and move the tool with the templet guide sliding
along the side of the templet.
NOTE:
• The workpiece will be cut a slightly different size from
the templet. Allow for the distance (X) between the bit
and the outside of the templet guide. The distance (X)
can be calculated by using the following equation:
Distance (X) = (outside diameter of the templet guide -
bit diameter) / 2 (Fig. 15)
Vacuum head set (Accessory) (Fig. 16,
Fig. 17 & Fig. 18)
Use the vacuum head for dust extraction. Install the
vacuum head on the tool base using the two screws.
Then connect a vacuum cleaner to the vacuum head.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
