FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.

Adjusting depth of cut (Fig. 1)

Loosen the wing bolt on the stopper. Move the stopper to the desired position and tighten the wing bolt. When tightened, the tip of the wing bolts should contact the flat surface of the stopper pole. The numbers indicated on the stopper pole are in cm units (3 mm per graduation).

Switch action (Fig. 2)

CAUTION:

- Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released.

To prevent the switch trigger from being accidentally pulled, a lock-off button is provided. To start the tool, push in the lock-off button and pull the switch trigger. Release the switch trigger to stop.

ASSEMBLY

CAUTION:

• Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

Installing or removing cutter chain (Fig. 3)

WARNING:

- Always be sure that the tool is switched off and unplugged before installing or removing the cutter chain.

- Always close the chain cover after installing, removing or adjusting the cutter chain.

To install the cutter chain, open the chain cover. Loosen the hex bolt securing the chain bar and the adjusting screw.

Orient the cutters in the direction of the arrow on the tool (rotational direction). Attach the cutter chain to the sprocket first and then to the chain bar. Semitighten the hex bolt. (Fig. 4)

Turn the adjusting screw to increase the tension on the cutter chain. Pull the middle of the cutter chain lightly. When there is a clearance of approx. 5 – 6 mm between the chain bar and the cutter chain, the tension on the cutter chain is adequate. (Fig. 5)

After adjusting the tension, tighten the hex bolt firmly to secure the chain bar. Additionally tighten slightly the adjusting screw. Close the chain cover.

To remove the cutter chain, follow the installation procedures in reverse.

Securing tool to workpiece (Fig. 6 & 7)

Loosen the vise lever and move the rear vise backward. Place the tool on the workpiece so that the front vise contacts the side of the workpiece. Move the rear vise forward until the distance between the rear vise and the workpiece is 3 – 8 mm. Tighten the vise lever to secure the rear vise. Move the tool so that the "0" on the indication plate is aligned with the cutting line (A). Push the lever (A) down fully to secure the workpiece. Turn the setting handle until the front edge of the yellow indicator plate is aligned with the cutting line (B). (Fig. 8)

OPERATION (Fig. 9)

Grasp firmly the grips on either side. Switch on the tool and wait until the cutter chain attains full speed. Then release the hook and lower the tool head to cut in the workpiece. Do not apply excessive pressure to the tool. This may not only decrease the working efficiency but also cause a dangerous reaction. Feed slowly at the beginning of a cutting operation, at the time of hole breakthrough and when cutting a knot in the workpiece. After cutting, gently raise the tool head until you can hook the tool head back onto the hook. Then switch off the tool. Raise the lever (A) and remove the tool from the workpiece.

WARNING:

• Always hook the tool head back onto the hook when not operating the tool.
• Never attempt to cut a twisted or warped workpiece which the tool is not secured firmly to.

Adjusting indicator plate and indication plate

The yellow indicator plate and indication plate are factory adjusted for the standard equipped cutter chain 16.5 mm. If the alignment is off, for some reason, or when using another size cutter chain, loosen the screws and adjust the yellow indicator plate and indication plate.

Enlarging hole

1. Transverse (width) enlargement (Fig. 10)

A hole can be enlarged transversely by adjusting the gauge plate. Max. expansion of hole width is 15 mm.

Example:

When cutting a hole 25 mm wide using a cutter chain 16.5 mm, proceed as follows:

• Push the lever (B) away from you. Loosen the hex bolts securing the gauge plate.
• Adjust the gauge plate so that the travel distance (D) is 8.5 mm; that is, 25 mm – 16.5 mm = 8.5 mm. Tighten the hex bolts to secure the gauge plate.
• Cut the first hole with the lever (B) pushed away from you. Then pull the lever (B) toward you and cut again to enlarge the hole.

NOTE:

- The gauge plate is factory adjusted for cutting a hole 30 mm wide.

2. Longitudinal (length) enlargement

Hole length can be determined in three steps shown in the table below.

Cutter chain position Hole length to be cut

Original position 52.5 mm

No.1 set position 52.5 mm – 105 mm

No.2 set position 77.5 mm – 130 mm

NOTE:

• A hole a little longer than predetermined may be cut depending upon the cutter chain tension.
• The adjusting hex bolts are factory adjusted for cutting holes 90 mm long in the No. 1 set position and 120 mm long in the No. 2 set position.

Push down the right-hand grip while raising the left-hand grip. Make sure that the adjusting hex bolt slips into place securely. (Fig. 11)

Loosen the hex nut securing the adjusting hex bolt. Turn the adjusting hex bolt until the cutter chain reaches the desired position, then tighten the hex nut. (Fig. 12)

WARNING:

- When using pressure to turn the adjusting hex bolt or hex nut, be careful not to allow the adjusting hex bolt to slip off the set position.

To bring the cutter chain back to the perpendicular (original) position, pull the lever (C) toward you while pressing down on the right-hand grip and slightly raising the left-hand grip and move the cutter chain back to its original position.

When cutting a hole, first use the perpendicular position, then No. 1 set position and finally No. 2 set position. Always safely hook the tool head back onto the hook when changing the cutter chain position. (Fig. 13)

When enlarging a hole both transversely and longitudinally, cut the holes in the order indicated from No. (1) to (6) as shown. This makes for more easy and efficient hole enlargement. (Fig. 14)

WARNING:

• Never attempt to enlarge a hole with the cutter chain still within the hole. This will cause unstable and dangerous operation.
• Never angle the cutter chain when cutting the first hole, or a dangerous kickback may result. Always have the cutter chain set to the perpendicular position when cutting the first hole.

Lap joints up to 130 mm can be cut with this tool. (Fig. 15)

NOTE:

- Lap joints can be cut only on the front (side away from you) of the workpiece.

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.

Replacing carbon brushes (Fig. 16)

Remove and check the carbon brushes regularly. Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes.

Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps. (Fig. 17)

Lubrication

After use, remove dirt, chips and foreign matter adhering to the tool. Then oil the moving parts (especially cutter chain) and the contact portions.

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.
