Frequently Asked Questions - CR13VBY HITACHI

How to change the blade of the Hitachi CR13VBY reciprocating saw?

Unplug the tool. Turn the collar (tool-less) counterclockwise to release the blade. Insert the new blade aligning the holes, then turn the collar the other way to lock. Check that the blade is securely attached before use.

How to adjust the cutting speed?

Use the speed adjustment wheel located on the handle. Turn it to increase or decrease the speed (0 to 2800 strokes/min). For hard materials, use a lower speed; for soft materials, a higher speed.

What type of blade to use for cutting metal?

Use a blade specifically for metal, with fine teeth (e.g., 14 teeth per inch). The recommended speed is low to medium to avoid overheating.

How to clean the saw after use?

Unplug the saw. Use a dry or slightly damp cloth to clean the housing and blade. Do not use harsh chemicals. Lightly lubricate the blade guide with appropriate oil.

The saw does not start, what to do?

Check that the plug is properly connected and the cable is not damaged. Make sure the safety lock is disengaged. If the problem persists, the motor brushes may be worn; replace them.

What is the maximum cutting depth in wood?

The maximum cutting capacity in wood is about 300 mm with an appropriate blade. For deeper cuts, use a longer blade (up to 400 mm).

How to use the anti-slip guide?

The anti-slip guide (metal shoe) should be pressed against the surface to be cut to stabilize the saw. It also allows you to follow the cutting line without deviating.

Where is the serial number of the saw located?

The serial number is engraved on the motor housing, usually near the handle or on the nameplate. It is required for after-sales service requests.

What are the main maintenance components?

The carbon brushes (to check every 50 hours of use), lubrication of the blade guide, and cleaning of ventilation slots. Use genuine Hitachi parts.

The saw vibrates abnormally, what to check?

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. 9, carry out lubrication around the blade holder on a periodic basis by use of cutting fluid, etc.

Fig. 9

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. 10 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.

Rubber cap

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)

Fig. 11

8. Adjusting the base

This unit employs a mechanism that can adjust the base mounting position in three

stages without the use of a wrench or other tools.

(1) Press a pushbutton. When you do this, a base lever will jump out to prepare the base for adjustment (Fig. 12)

Fig. 12

(2) Push up the base tip and jog the base back and forth. (Fig. 13)

Fig. 13

(3) You can adjust the base position in three stages. Move the base at an interval of about 15 mm, find the position where the base hooks, and press in the base lever with your fingers. The base is secured when you hear the clicking sound. (Fig. 14)

Fig. 14

1. Adjusting the blade reciprocating speed

This unit has a built-in electronic control circuit that makes it possible to adjust the variable speed of the saw blade either both by pulling a switching trigger or turning a dial. (Fig. 15)

Fig. 15
(1) If you pull the trigger further in, the speed of the blade accelerates. Begin cutting at a low speed to ensure the accuracy of your target cut position. Once you've obtained a sufficient cutting depth, increase the cutting speed.

(2) On the dial scale, "5" is the maximum speed and "1" the minimum. The high speed is generally suitable for soft materials such as wood, and the low speed is suitable for hard materials such as metal. We recommend that you use the following as a rough guide in selecting the suitable speed for the materials you are cutting.

Example of materials Recommended to be cut dial scale
Mild steel pipes / cast-iron tubes / 2 – 4 L-shaped angle steel
Wood / wood with nails driven in	5
Stainless steel 1 – 3
Aluminum / brass / copper 2 – 4
Plaster board 4 – 5
Plastic / fiber board 1 – 3

CAUTION:

When cutting at low speed (scale of 1 – 2), never cut a wooden board more than 25/64" (10 mm) thick or a mild steel plate more than 5/64" (2 mm) thick. The load

on the motor can result in overheating and damage.

Although this unit employs a powerful motor, prolonged use at a low speed will increase the load unduly and may lead to overheating. Properly adjust the saw blade to allow steady, smooth cutting operation, avoiding any unreasonable use such as sudden stops during cutting operation.

1. Adjusting the swing cutting operation Two cutting systems can be selected with this unit. The first is straight cutting, in which the saw blade is moved linearly, and the second is the swing cutting, in which the saw blade is swung like a pendulum. (Fig. 16, Fig. 17)

(1) Straight cutting

You can perform straight cutting by setting the change lever widthwise. Straight cutting should normally be performed when cutting hard materials such as metal, etc. (Fig. 16)

Straight cutting

Fig. 16

(2) Swing cutting

You can perform swing cutting by setting the change lever lengthways.

Swing cutting should normally be performed when cutting soft materials such as wood, etc.

Swing cutting is efficient since the saw blade forcibly bites into the material. (Fig. 17)

Change lever

Fig. 17

CAUTION:

○ Even for soft materials, you should perform straight cutting if you wish to make curved or clean cuts.

○ Dust and dirt accumulated on the change lever section can degrade the function of the change lever. Periodically clean the change lever section.

When performing swing cutting, use a saw with straight blade. If a saw with curved blade is used, the saw blade may be broken or the unit may be damaged.

HOW TO USE THE RECIPROCATING SAW

CAUTION:

○ Avoid carrying it plugged to the outlet with your finger on the switch. A sudden startup can result in an unexpected injury.

○ 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.

○ Do not remove the front cover (refer to Fig. 2).

Hold firmly the front cover by hand to operate.

But, do not extend your hand or finger beyond the flange (see Fig.18) of front cover to avoid an injury.

○ 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.

○ 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 (see Fig. 18 and Fig. 19).

Fig. 18

Fig. 19

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. 20, Fig. 21)

Fig. 21

To maximize cutting efficiency for the materials you are using and working conditions, adjust the speed of the saw blade and the switching to swing cutting.

1. Cutting metallic materials

CAUTION:

○ Press the base firmly against the workpiece.
Never apply any unreasonable force to the saw blade when cutting. Doing so can easily break the blade.

(1) Fasten a workpiece firmly before operation. (Fig.22)

Technical line drawing of a hand using a tool to adjust or install a mechanical component (no text or symbols present)

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) Use the dial to adjust the speed of the saw blade to suit your working conditions and materials.

(4) You can cut smoothly if you set the change lever position to straight cutting (Fig. 16).

2. Cutting lumber

(1) When cutting lumber, make sure that the workpiece is fastened firmly before beginning. (Fig. 23)

Technical line drawing of a hand using a tool to adjust or install a mechanical component (no text or symbols present)

Fig. 23

(2) You can cut efficiently if the speed of the saw blade is set to dial scale "5".
(3) You can cut efficiently if the change lever position is set to swing cutting (Fig. 17). Alternatively, you can cut cleanly if the change lever position is set to straight cutting (Fig. 16).

CAUTION:

Never apply any unreasonable force to the saw blade when cutting. Also remember to press the base against the lumber firmly.

3. Sawing curved lines

We recommend that you use the BIMETAL blade mentioned in Page 18 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.

4. Plunge cutting

With this tool, you can perform pocket 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. 27, and Fig. 29. 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 18. 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)

CAUTION:

○ Avoid plunge cutting for metallic materials. This can easily damage the blade.

Never pull the switch trigger while the tip of the saw blade tip is pressed against the material. If you do so, the blade can easily be damaged when it collides with the material.

○ 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.

MAINTENANCE AND INSPECTION

⚠ WARNING: Be sure to switch power OFF and disconnect the plug from the receptacle during 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 loosened, retighten them immediately.

WARNING: Using this reciprocating saw with loosen screws is extremely dangerous.

1. 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.

2. Inspecting the carbon brushes (Fig. 30) The Motor employs carbon brushes which are consumable parts. When they become worn to or near the "wear limit", it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

Fig. 30

NOTE: Use HITACHI carbon brush No. 43 indicated in Fig. 30.

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

2. Service and repairs All quality power tools will eventually require servicing or replacement of parts because of wear from normal use. To assure that only authorized replacement parts will be used, all service and repairs must be performed by a HITACHI AUTHORIZED SERVICE CENTER, ONLY.

3. Service parts list

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints,
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
