转至面朝下，锯条应自然落下，若未自然落下请用手将其拔出。

注意

切勿用手触摸刚刚使用过的锯条，否则，灼热的金属极易烫伤您的皮肤。

当锯条损坏时

即使当刀刃破损并残留在柱塞的小缝隙内时，若按箭头标记的方向推动手柄并使刀刃朝下，它仍会自行掉下。若未自行掉下，请按下述步骤将它取出。

(1) 损坏的锯条的某部分粘在了插条的小插槽中，拔

出插条并将锯条拔出。

(2) 若损坏的锯条藏在小插槽内部，请用锯条的尖部

将其钩住并取出。（图 11）

电锯的维护和检查

(1) 使用后，请用气刷或刷子清除掉锯条上的灰尘、

泥土、尘沙或潮气等，以确保锯条的工作顺畅。

(2) 如图 12 所示，定期使用切锯液等在刀刃周围涂上

润滑油。

注

若在不乾净或未润滑刀刃的状态下使用工具，手柄的功能可能因积尘和碎屑而变得重滞。在这种情况下，按图 13 所示的箭头标记方向拉动安装在手柄上的橡皮盖，并将其从手柄上取下。然後，使用气刷或类似工具清洁刀刃座内部，并涂上适量的润滑油。朝手柄用力按压橡皮盖可将其安装上。此时请确定刀刃座与橡皮盖之间没有缝隙，并确保所安装的刀刃工作正常。

4. 切锯曲线

建议使用表 7（参照第 12 页）中的 BI-METAL 刀刃，因为这种刀刃坚韧耐用。

注意

将材料切割成小圆弧时须降低进料速度，速度过快可能会损坏刀刃。

5. 插入切锯

使用本电动往复锯，可在木合板和薄板材料上进行插入切锯。如图 25、图 26、和图 27 所示，颠倒安装刀刃，可相当轻松地进行袋形切锯。请尽量使用短而薄的刀刃。为此，建议使用第 12 页表 7 中列出的 BI-METAL 刀刃号码 132 号。在切锯作业中请务必小心操作并遵守以下步骤。

(1) 请将底座的下部（或上部）压在切锯材料上，使

刀刃前端脱离切锯材料并扣扳机。（图 24，图 25）

(2) 慢慢抬起把手并用刀刃一点一点地切入。（图

26，图 27）

(3) 紧紧抓住机身，直至刀刃完全切入材料。（图

28，图 29）

注意

䡬避免对金属材料进行切锯，否则很容易损坏刀

刃。

䡬在刀刃前端压在切锯材料上时切勿扣扳机。否

则，当刀刃接触材料时很容易被损坏。

䡬务必紧紧抓住机身缓慢地进行切锯。在切锯作

业中若对刀刃异常用力，则很容易损坏刀刃。

注

在寒冷的条件（低于摄氏零度）下使用电池 EB1826HL 和 EB1830HL 会减弱转动扭力和减少工作量。这只是暂时现象。在电池变热后会恢复正常。

NOTE

The recharging time may vary according to temperature and power source voltage.

4. Disconnect the charger’s power cord from the

receptacle

5. Hold the charger firmly and pull out the battery

NOTE

After operation, pull out batteries from the charger first, and then keep the batteries properly.

Regarding electric discharge in case of new batteries, etc.

As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be short when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2 – 3 times.

How to make the batteries perform longer.

(1) Recharge the batteries before they become

completely exhausted. When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.

(2) Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has been cooled for a while.

CAUTION

䡬 If the battery is charged while it is heated because

it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights up green. In such a case, first let the battery cool, then start charging.

䡬 When the pilot lamp flickers in red quickly (at 0.2-

second intervals), check for and take out any foreign objects in the charger’s battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

䡬 Since the built-in micro computer takes about 3

seconds to confirm that the battery being charged with UC24YFA is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

PRIOR TO OPERATION

1. Mounting the blade

This unit employs a detachable mechanism that enables mounting and removal of saw blades without the use of a wrench or other tools.

(1) Turn on and off the switching trigger several times

so that the lever can jump out of the front cover completely. Thereafter, turn off the switch and remove the battery (Fig. 5).

CAUTION

Be absolutely sure to keep the switch turned off and the battery removed to prevent any accident.

(2) Push the lever in the direction of the arrow mark

shown in Fig. 6 marked on the lever (Fig. 6).

(3) Insert the saw blade all the way into the small slit

of the plunger tip with the lever pushing. You can mount this blade either in the upward or downward direction (Fig. 7, Fig. 8).

(4) When you release the lever, the spring force will

return the lever to the correct position automatically (Fig. 9).

(5) Pull the back of the saw blade two or three times

by hand and check that the blade is securely mounted. When pulling the blade, you will know it is properly mounted if it clicks and the lever moves slightly (Fig. 10).

CAUTION

When pulling the saw blade, be absolutely sure to pull it from the back. Pulling other parts of the blade will result in an injury.

2. Dismounting the blade

(1) Turn on and off the switching trigger several times

so that the lever can jump out of the front cover completely. Thereafter, turn off the switch and remove the battery (Fig. 5).

CAUTION

Be absolutely sure to keep the switch turned off and the battery removed to prevent any accident.

(2) After you have pushed the lever in the direction

of the arrow mark shown in Fig. 6 and secured it, turn the blade so it faces downward. The blade should fall out by itself. If the blade doesn’t fall out, pull it out by hand.

CAUTION

Never touch the saw blade immediately after use. The metal is hot and can easily burn your skin.

WHEN THE BLADE IS BROKEN

Even when the saw blade is broken and remains inside the small slit of the plunger, it should fall out if you push the lever in the direction of the arrow mark, and face the blade downward. If it doesn’t fall out itself, take it out using the procedures explained below.

(1) If a part of the broken saw blade is sticking out

of the small slit of the plunger, pull out the protruding part and take the blade out.

(2) If the broken saw blade is hidden inside the small

slit, hook the broken blade using a tip of another saw blade and take it out (Fig. 11).

MAINTENANCE AND INSPECTION OF SAW BLADE MOUNT

(1) After use, blow away sawdust, earth, sand, moisture,

etc., with air or brush them away with a brush, etc., to ensure that the blade mount can function smoothly.

(2) As shown in Fig. 12, carry out lubrication around

the blade holder on a periodic basis by use of cutting fluid, etc.

NOTE

Continued use of the tool without cleaning and lubricating the area where the saw blade is installed can result in some slack movement of the lever due to accumulated sawdust and chips. Under the circumstances, pull a rubber cap provided on the lever in the direction of an arrow mark as shown in Fig. 13 and remove the rubber cap from the lever. Then, clean up the inside of the blade holder with air and the like and carry out sufficient lubrication. The rubber cap can be fitted on if it is pressed firmly onto the lever. At this time, make certain that there exists no clearance between the blade holder and the rubber cap, and furthermore ensure that the saw-blade-installed area can function smoothly.

CAUTION

Do not use any saw blade with a worn-out blade hole. Otherwise, the saw blade can come off, resulting in personal injury (Fig. 14).

3. Moving the base

Loosen the set screw and move the base forward, as shown in Fig. 15, Fig. 16. Tighten the set screw slightly, ensure the base does not move back and forth, and firmly tighten the set screw. Ensure that the base does not contact the blade.

4. Confirm that the battery is mounted correctly

HOW TO USE

CAUTION

䡬 Do not carry tools with your finger on the switch.

A sudden startup can result in an unexpected injury.

䡬 Be careful not to let sawdust, earth, moisture, etc.,

enter the inside of the machine through the plunger section during operation. If sawdust and the like accumulate in the plunger section, always clean it before use (refer to Fig. 5).

䡬 Do not remove the front cover.

Be sure to hold the body from the top of the front cover (refer to Fig. 5).

䡬 During use, press the base against the material

while cutting. Vibration can damage the saw blade if the base is not pressed firmly against the workpiece. Furthermore, a tip of the saw blade can sometimes contact the inner wall of the pipe, damaging the saw blade.

䡬 Select a saw blade of the most appropriate length.

Ideally, the length protruding from the base of the saw blade after subtracting the stroke quantity should be larger than the material (see Fig. 18 and Fig. 20). If you cut a large pipe, large block of wood, etc., that exceeds the cutting capacity of a blade; there is a risk that the blade may contact with the inner wall of the pipe, wood, etc., resulting in damage (Fig. 19, Fig. 21).

1. Switch operation

(1) Lock-off button

The tool is equipped with a lock-off button. To activate the trigger lock, move the button to the right position. Move the button to the left to operate the tool (Fig. 17). Always lock the switch when carrying or storing the tool eliminate unintentional starting.

(2) Trigger switch

This tool is equipped with a variable speed controlled trigger switch. The tool can be turned "ON" or "OFF" by squeezing or releasing the trigger. The blade plunger stroke rate can be adjusted from the minimum to maximum nameplate stroke rate by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed.

2. Cutting metallic materials CAUTION

䡬 Press the base firmly against the workpiece. 䡬 Never apply any unreasonable force to the saw

blade when cutting. Doing so can easily break the blade.

䡬 The motor can be locked sometimes, depending on

the combination of the material to be cut and the blade. Whenever the motor gets locked, switch it

off immediately. (1) Fasten a workpiece firmly before operation (Fig. 22). (2) When cutting metallic materials, use proper machine

oil (turbine oil, etc.). When not using liquid machine

oil, apply grease over the workpiece.

CAUTION

The service life of the saw blade will be drastically

shortened if you don’t use machine oil.

3. Cutting lumber

When cutting lumber, make sure that the workpiece

is fastened firmly before beginning (Fig. 23).

CAUTION

䡬 Never apply any unreasonable force to the saw

blade when cutting. Also remember to press the

base against the lumber firmly.

4. Sawing curved lines

We recommend that you use the BI-METAL blade

mentioned in Table 7 (Page 20) for the saw blade

since it is tough and hardly breaks.

CAUTION

Delay the feed speed when cutting the material into

small circular arcs. An unreasonably fast feed may

break the blade.

5. Plunge cutting

With this tool, you can perform plunge cutting on

plywood panels and thin board materials. You can

carry out pocket cutting quite easily with the saw

blade installed in reverse as illustrated in Fig. 25,

Fig. 26, and Fig. 27. Use the saw blade that is as

short and thick as possible. We recommend for this

purpose that you use BI-METAL Blade No. 132

mentioned in Page 20, Table 7. Be sure to use

caution during the cutting operation and observe

the following procedures. (1) Press the lower part (or the upper part) of the base

against the material. Pull the switch trigger while

keeping the tip of the saw blade apart from the

material (Fig. 24, Fig. 25). (2) Raise the handle slowly and cut in with the saw

blade little by little (Fig. 26, Fig. 27). (3) Hold the body firmly until the saw blade completely

cuts into the material (Fig. 28, Fig. 29).

CAUTION

䡬 Avoid plunge cutting for metallic materials. This can

easily damage the blade. 䡬 Never pull the switch trigger while the tip of the

saw blade is pressed against the material. If you

do so, the blade can easily be damaged when it collides with the material.

䡬 Make absolutely sure that you cut slowly while

holding the body firmly. If you apply any unreasonable force to the saw blade during the cutting operation, the blade can easily be damaged.

NOTE

The use of the battery EB1826HL and EB1830HL in a cold condition (below 0 degree Centigrade) can sometimes result in the weakened cutting torque and reduced amount of work. This, however, is a temporary phenomenon, and returns to normal when the battery warms up.

SELECTION OF BLADES

To ensure maximum operating efficiency and results, it is very important to select the appropriate blade best suited to the type and thickness of the material to be cut.

NOTE

䡬 Dimensions of the workpiece mentioned in the table

represent the dimensions when the mounting position of the base is set nearest to the body of the Cordless Reciprocating Saw. Caution must be exercised since dimensions of the workpiece will become smaller if the base is mounted far away from the body of the Cordless Reciprocating Saw.

MAINTENANCE AND INSPECTION

CAUTION

Be sure to turned off the switch and remove the battery before maintenance and inspection.

1. Inspecting the blade

Continued use of a dull or damaged blade will result in reduced cutting efficiency and may cause overloading of the motor. Replace the blade with a new one as soon as excessive abrasion is noted.

2. 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.

3. 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.

4. Inspecting the carbon brushes (Fig. 30)

The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones when it becomes worn to or near the "wear limit". In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

NOTE

When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No.

999058.

5. Replacing carbon brushes

Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a flat head screw driver, etc., as shown in Fig. 32. When installing the carbon brush, choose the direction so that the nail of the carbon brush agrees with the contact portion outside the brush tube. Then push it in with a finger as illustrated in

Fig. 33. Lastly, install the brush cap.

CAUTION

Be absolutely sure to insert the nail of the carbon brush into the contact portion outside the brush tube (You can insert whichever one of the two nails provided). Caution must be exercised since any error in this operation can result in the deformed nail of the carbon brush and may cause motor trouble at an early stage.

6. Cleaning of the outside

When the Cordless Reciprocating Saw is stained, wipe with a soft dry cloth or a cloth moistened with soapy water. Do not use chloric solvents, gasoline or paint thinner, as they melt plastics.

7. Storage

Store the Cordless Reciprocating Saw in a place in which the temperature is less than 40°C, and out of reach of children.
