SAFETY INSTRUCTIONS FOR MITER SAW

a) Miter saws are intended to cut wood or wood-like products, they cannot be used with abrasive cutoff wheels for cutting ferrous material such as bars, rods, studs, etc.
Abrasive dust causes moving parts such as the lower guard to jam. Sparks from abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
b) Use clamps to support the workpiece whenever possible. If supporting the workpiece by hand, you must always keep your hand at least 100 mm from either side of the saw blade. Do not use this saw to cut pieces that are too small to be securely clamped or held by hand.
If your hand is placed too close to the saw blade, there is an increased risk of injury from blade contact.
c) The workpiece must be stationary and clamped or held against both the fence and the table. Do not feed the workpiece into the blade or cut “freehand” in any way.
Unrestrained or moving workpieces could be thrown at high speeds, causing injury.
d) Never cross your hand over the intended line of cutting either in front or behind the saw blade. Supporting the workpiece “cross handed” i.e. holding the workpiece to the right of the saw blade with your left hand or vice versa is very dangerous.
e) Do not reach behind the fence with either hand closer than 100 mm from either side of the saw blade, to remove wood scraps, or for any other reason while the blade is spinning. The proximity of the spinning saw blade to your hand may not be obvious and you may be seriously injured.
f) Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp it with the outside bowed face toward the fence. Always make certain that there is no gap between the workpiece, fence and table along the line of the cut.
Bent or warped workpieces can twist or shift and may cause binding on tile spinning saw blade while cutting. There should be no nails or foreign objects in the workpiece.
g) Do not use the saw until the table is clear of all tools, wood scraps, etc., except for the workpiece.
Small debris or loose pieces of wood or other objects that contact the revolving blade can be thrown with high speed.
h) Cut only one workpiece at a time.
Stacked multiple workpieces cannot be adequately clamped or braced and may bind on the blade or shift during cutting.
i) Ensure the miter saw is mounted or placed on a level, firm work surface before use.
A level and firm work surface reduces the risk of the miter saw becoming unstable.
j) Plan your work. Every time you change the bevel or miter angle setting, make sure the adjustable fence is set correctly to support the workpiece and will not interfere with the blade or the guarding system.
Without turning the tool “ON” and with no workpiece on the table, move the saw blade through a complete simulated cut to assure there will be no interference or danger of cutting the fence.
k) Provide adequate support such as table extensions, saw horses, etc. for a workpiece that is wider or longer than the table top.
Workpieces longer or wider than the miter saw table can tip if not securely supported. If the cut-off piece or workpiece tips, it can lift the lower guard or be thrown by the spinning blade.
l) Do not use another person as a substitute for a table extension or as additional support.
Unstable support for the workpiece can cause the blade to bind or the workpiece to shift during the cutting operation pulling you and the helper into the spinning blade.
m) The cut-off piece must not be jammed or pressed by any means against the spinning saw blade.
If confi ned, i.e. using length stops, the cut-off piece could get wedged against the blade and thrown violently.
n) Always use a clamp or a fi xture designed to properly support round material such as rods or tubing.
Rods have a tendency to roll while being cut, causing the blade to “bite” and pull the work with your hand into the blade.
o) Let the blade reach full speed before contacting the workpiece.
This will reduce the risk of the workpiece being thrown.
p) If the workpiece or blade becomes jammed, turn the miter saw off . Wait for all moving parts to stop and disconnect the plug from the power source and/or remove the battery pack. Then work to free the jammed material.
Continued sawing with a jammed workpiece could cause loss of control or damage to the miter saw.
q) After finishing the cut, release the switch, hold the saw head down and wait for the blade to stop before removing the cut-off piece.
Reaching with your hand near the coasting blade is dangerous.
r) Hold the handle fi rmly when making an incomplete cut or when releasing the switch before the saw head is completely in the down position.
The braking action of the saw may cause the saw head to be suddenly pulled downward, causing a risk of injury.

Drop the head and insert the locking pin (page 14 “4. Releasing the locking pin”).
Turn and loosen the side handle, turn the turntable as far right as it will go, and secure the turntable by turning the handle to the fixed position. This will make the main body
even more compact.
When transporting the main body, carry it in your arms, holding the grip located on the base with both hands or carry handle.

MAINTENANCE AND INSPECTION

WARNING
To avoid an accident or personal injury, always confi rm the trigger switch is turned OFF and that the battery has been disconnected from the power tool before performing any maintenance or inspection of this tool.
Report to qualifi ed person as soon as possible, if you discover the fault of machine including guards or blade saw.

1. Inspecting the saw blade
   Always replace the saw blade immediately upon the first sign of deterioration or damage.
   A damaged saw blade can cause personal injury and a worn saw blade can cause ineffective operation and possible overload to the motor.
   CAUTION
   Never use a dull saw blade. When a saw blade is dull, its resistance to the hand pressure applied by the tool handle tends to increase, making it unsafe to operate the power tool.

2. About Handling the Motor (see Fig. 2)
   Winding of the motor is said to be the heart of this tool. Exercise utmost caution not to damage the winding by exposing it to wash oil or water.
   NOTE
   Accumulation of dust and the like inside the motor can result in a malfunction.
   After using the motor for 50 hours or so, carry out no-load running, and blow in the dry air from a wind hole at the motor’s rear. Such action is effective to discharge dust and the like.

3. Inspecting the lever
   If the M6 hexagonal head bolts (2) are loose, align the sides of the fence and saw blade with the steel square. After adjusting the saw blade and fence to a ninety-degree angle, tighten the lever securing hexagonal head bolts (2).
   

4. Inspecting the screws
   Regularly inspect each component of the power tool for looseness.
   Re-tighten screws on any loose part.
   WARNING
   To prevent personal injury, never operate the power tool if any components are loose.

5. Inspecting the lower guard for proper operation
   Before each use of the tool, test the lower guard (see Fig. 14) to assure that it is in good condition and that it moves smoothly.
   Never use the tool unless the lower guard operates properly and it is in good mechanical condition.

6. Inspection of terminals (tool and battery)
   Check to make sure that swarf and dust have not collected on the terminals.
   On occasion check prior, during and after operation.
   CAUTION
   Remove any swarf or dust which may have collected on the terminals.
   Failure to do so may result in malfunction.

7. Disposal of the exhausted battery
   WARNING
   Do not dispose of the exhausted battery. The battery must explode if it is incinerated. The product that you have purchased contains a rechargeable battery. The battery is recyclable. At the end of it’s useful life, under various state and local laws, it may be illegal to dispose of this battery into the municipal waste stream. Check with your local solid waste offi cials for details in your area for recycling options or proper disposal.

8. Storage
   After operation of the tool has been completed, check that the following has been performed:

9. Trigger switch is in OFF position,

10. Pull out the battery from the tool.
    When the tool is not in use, storing in a place below 104°F (40°C) and out of the reach of children.
    NOTE
    Storing lithium-ion batteries
    Make sure the lithium-ion batteries have been fully charged before storing them.
    Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, signifi cantly reducing battery usage time or rendering the batteries incapable of holding a charge.
    However, signifi cantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to fi ve times.
    If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.

11. Lubrication
    Lubricate the following sliding surfaces once a month to keep the power tool in good operating condition for a long time (see Fig. 2 and Fig. 3). Use of machine oil is recommended.
    Oil supply points:
    ○ Rotary portion of hinge
    ○ Rotary portion of vise assembly
    ○ Rotary portion of holder (A)

12. Cleaning Clean the machine, duct and lower guard by blowing with dry air from an air gun or other tool. (Fig. 40) Periodically remove chips, dust and other waste material from the surface of the power tool, especially from the inside of the lower guard with a damp, soapy cloth. To avoid a malfunction of the motor, protect it from contact with oil or water.
