NOTE
Be sure to pull out the battery from the battery charger after use, and then keep it.
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 low when using them the first and second time. This is a temporary phenomenon, and the 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 cooled for a while.

CAUTION

• When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give 15 minutes rest until the next charging.
• 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 for 1 second, but does not light for 0.5 seconds (off for 0.5 seconds). The battery will not be recharged. In such a case, let the battery cool before charging.
• When the pilot lamp fl ickers (at 0.2-second intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning.   Take it to your authorized Service Center.

2. If the broken saw blade is hidden inside the slit, hook the broken blade using the tip of another saw blade and take it out. (Fig. 10)

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.
NOTE
Continued use of the tool without cleaning the area where the saw blade is attached can result in sawdust and chip buildup which may adversely aff etc the movement of the blade holder. Should this be the case, pivot the blade holder and clean around the blade holder by wiping or blowing away the buildup?
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. 11)

5. Adjusting the base (Fig. 12)
To maximize blade life, the base slides in or out to allow the stroke length to be adjusted for better effi ciency.
(1) Remove the hexagonal bar wrench from its storage spot, and use it to loosen the 2 base stopper screws at the bottom of the front cover.
(2) Adjust the attachment position of the base.
(3) Firmly tighten the 2 base stopper screws that were loosened.

WARNING
To avoid injury and damage, do not operate the saw without the base in place. The blade holder may strike against the workpiece and damage the reciprocating mechanism.

6. Check battery insertion

WARNING
If the battery is inserted while the power switch is in the ON position, the power tool will start operating immediately, inviting serious accidents.

CAUTION
Until the battery locks in place with a little click, if not, it may accidentally fall out of the tool causing injury to you or someone around you.

**HOUSING THE HEXAGONAL BAR WRENCH![metabo CR18DB Cordless Reciprocating Saw

• FIG 16](https://manuals.plus/wp-content/uploads/2022/07/metabo-CR18DB- Cordless-Reciprocating-Saw-FIG-16.png)**

OPERATION

WARNING

• Never touch the moving parts.

• Do not remove the front cover (refer to Fig. 2).
  Be sure to hold the body from the top of the front cover.
  CAUTION

• 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.

• During use, press the base against the material while cutting.
  Vibration can damage the saw blade if the base is not pressed fi rmly against the workpiece. Furthermore, the tip of the saw blade can sometimes contact the inner wall of the pipe, damaging the saw blade.

• Select a saw blade of the most appropriate length. Ideally, the length protruding from the base of the saw blade after subtracting the stroke should be larger than the material (Fig. 14). 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. 15)

• To extend the lifetime, the lithium-ion battery equips with the protection function to stop the output. Therefore, if the tool is overloaded, the motor may stop. However, this is not the trouble but the result of the protection function. In this case, release the switch of tool and eliminate the causes of overloading.
  

• Don’t remove the tool from the workpiece during a cut while the saw blade is moving.
  

NOTE
Take care not to lock the motor. If the motor is locked, immediately turn the power off. If the motor is locked for a while, the motor or battery may be burnt.
1. Switch operation
(1) Lock-off button
The tool is equipped with a lock-off button. To start the tool, press the lock- off button and then squeeze the trigger switch. (Fig. 16)

CAUTION
Do not fix and secure the lock-off button.
Besides, keep your finger off the trigger switch when the tool is being carried around. Otherwise, the trigger switch can be inadvertently turned ON, resulting in unexpected accidents.
(2) Trigger switch (Fig. 17)
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 the speed. 2. Stroke Mode
This power tool features a straight mode in which the blade moves back and forth and an orbital mode in which the blade moves back and forth while moving up and down.
For soft materials such as wood, the orbital model ensures smooth cutting operation while improving the discharge of sawdust and the interlock with materials. Use the change lever to select the ideal model for the task at hand. (Fig. 18)
The ideal model depends on factors such as the hardness of the material to be cut and the level of finish required. Use Table 5 as a guideline when making your choice.

Table 5

down action
Hardness of Material| Hard material| | Soft material
Cutting Speed| Slow| | Fast
Level of Finish| Smooth| | Rough

NOTE

• To select the stroke mode, operate the change lever when the product is completely stopped.
• Select Straight Mode if you wish to cut soft materials neatly.
• Occasionally clean the change lever as its movement may be adversely aff ected if dirt or dust collects on the change lever.
