Ensure that the power switch is in the OFF position. If the plug is connected to a receptacle while the power switch is in the ON position, the power tool will start operating immediately, which could cause a serious accident.

3. Extension cord

When the work area is removed from the power source, use an extension cord of sufficient thickness and rated capacity. The extension cord should be kept as short as practicable.

INSTALLING AND REMOVING BITS

WARNING:

Be sure to switch power OFF and disconnect the plug from the receptacle to avoid serious trouble.

1. Installing bits

(1) Remove the motor housing from base as follows.

(a) Open the lever. (Fig. 1)

Fig. 1

(b) While holding the base, turn the motor housing counterclockwise.
(c) Turn it until the pin in the base is disengaged from the groove in the motor housing. Lift the motor housing free from the base.

(2) Clean and insert shank of bit into the collet chunk until shank bottoms, then back it out approximately 2 mm.

(3) With the bit inserted and 16 mm wrench holding the armature shaft, use the 23 mm wrench to firmly tighten the collet chuck in a clockwise direction (viewed from under the router). (Fig. 2)

Fig. 2

(4) When using the 8 mm diameter shank bit, replace the equipped collet chuck with the one for 8 mm diameter shank bit which is provided as the standard accessory.

CAUTION:

Ensure that the collet chuck is firmly tightened after inserting a bit. Failure to do so will result in damage to the collet chuck.

2. Removing bits

When removing the bits, do so by following the steps for installing bits in reverse order.

INSTALLING THE MOTOR HOUSING

WARNING:

Be sure to switch power OFF and disconnect the plug from the receptacle to avoid serious trouble.

1. Installing the motor housing

(1) Open the lever.
(2) While holding the base, insert the motor housing into the base aligning the pin with the groove in the base.
(3) Confirm that the pin and the groove are aligning. Rotate the motor housing clockwise into the base.
(4) Close the lock lever.

Fig. 3

CAUTION:

You should be able to clamp the locking lever without excessive force. Excessive force may damage the base. You should not be able to move the motor in the base when the lever is clamped. To adjust the lever's clamping force, open the locking lever and turn the knob nut in small increments. Turning the knob nut clockwise tightens the lever, while turning the knob nut counterclockwise loosens the lever.

HOW TO USE THE ROUTER

WARNING:

Be sure to switch power OFF and disconnect the plug from the receptacle to avoid serious trouble.

1. Adjusting depth of cut

(1) Place the tool on a flat wood surface.
(2) Open the lever and turn the motor housing until the bit just touches the flat surface. (Fig. 4)

Fig. 4

(3) Clamp the lever down until the point where a click can be felt. (Fig. 5)

Fig. 5

NOTE:

The motor housing can be temporarily secured by clamping the lever (the motor housing does not slide down by its own weight).

If the motor housing slides down, make adjustments by tightening the knob nut.

Turning the knob nut clockwise tightens the lever, while turning the knob nut counterclockwise loosens the lever.

(4) While holding up the base slightly, turn the motor housing clockwise until the index line on the motor housing reaches the desired depth indicated on the scale ring. (Fig. 4)

(5) Close the lever firmly.

2. Guiding the router

(1) Template Guide:

Use the template guide when employing a template for producing a large quantity of identically shaped products.

As shown in Fig. 6, secure the template guide to the base of the router with two accessory screws. At this time, ensure that the projection side of the template guide is facing the bottom surface of the base of the router.

Fig. 6

A template is a profiling mold made of plywood or thin lumber. When making a template, pay particular attention to the matters described blow and illustrated in Fig. 7.

When using the router along the interior plane of the template, the dimensions of the finished product will be less than the dimensions of the template by an amount equal to dimension "A", the difference between the radius of the template guide and the radius of the bit. The reverse is true when using the router along the exterior of the template.

Fig. 7

Secure the template to the workpiece. Feed the router in the manner that the template guide moves along the template as shown in Fig. 8.

Fig. 8

(2) Straight guide

Use straight guide for chamfering and groove cutting along the materials side.

①Insert the guide bar into the hole in the bar holder, then lightly tighten the 2 wing bolts (A) on top of the bar holder.
②Insert the guide bar into the hole in the base, then firmly tighten the 2 hex socket bolts (standard accessories).
③Make minute adjustments of the dimensions between the bit and the guide surface with the feed screw, then firmly tighten the 2 wing bolts (A) on top of the bar holder and the wing bolt (B) that secures the straight guide. (Fig. 9)

Fig. 9

④As shown in Fig. 10, securely attach the bottom of the base to processed surface of the materials. Feed the router while keeping the guide plane on the surface of the materials.

5. Cutting WARNING

○Wear eye protection when operating this tool.

Keep your hands, face and other body parts away from the bits and any other rotating parts, while operating the tool.

(1) The bit must be kept clear of the materials which are to be cut, when the power is being turned on. (Fig. 11)

Fig. 11

(2) Then turn the tool on and wait until the bit attains full speed.

(3) The bit rotates clockwise (arrow direction indicated on the base). To obtain maximum conformance with the feed directions shown in Fig. 12.

    B --> C["Rotation of bit"]
    C --> D["Return to Router feed"]

Fig. 12

NOTE:

○ Moving the tool forward 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.

○Abnormalities and overloads will trigger the overload protector, and stop operation. Remove the load immediately, and turn the power off, then on. The rotation speed should return to normal.
○Do not use a power generator as the power source. It may cause the rotation speed to fluctuate.
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.

MAINTENANCE AND INSPECTION

1. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so could result in serious hazard.

2. Maintenance of the motor

The motor unit winding is the very "heart" of the power tool.

Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

3. Inspecting the carbon brushes (Fig. 13)

The motor employs carbon brushes which are consumable parts. Since an excessively worn carbon brush can result in motor trouble, replace the carbon brushes with new ones having the same carbon brush No. shown in the figure when it becomes worn to or near the "wear limit". In addition, always keep carbon brushes clean and ensue that they slide freely within the brush holders.

Fig. 13

4. Replacing carbon brushes:

Disassemble the brush caps with a slotted-head screwdriver. The carbon brushes can then be easily removed.
