MAKITA DHS780 (01) PDF Document

The tool is intended for performing lengthways and crossways straight cuts and miter cuts with angles in wood while in firm contact with the workpiece. With appropriate Makita genuine saw blades, other materials can also be sawed.

To install: Align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely.

To remove: Loosen the lever for depth adjustment to lower the tool base. Then slide the battery from the tool while sliding the button on the front of the cartridge.

Always switch off the tool before installing or removing the battery cartridge. Hold the tool and the battery cartridge firmly when installing or removing.

If your battery cartridge has an indicator, press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps light up for a few seconds.

Additionally, the tool itself has a battery indicator. Press the check button on the tool to indicate the remaining battery capacities. The battery indicators correspond to each battery.

The tool is equipped with a tool/battery protection system that automatically cuts off power to the motor to extend tool and battery life. The tool will automatically stop during operation under the following conditions:

Overload protection: When the tool is operated in a manner that causes it to draw an abnormally high current, the tool automatically stops. Turn the tool off and stop the application that caused the overload. Then turn the tool on to restart.

Overheat protection: When the tool is overheated, the tool stops automatically, and the battery indicator blinks for about 60 seconds. Let the tool cool down before turning it on again.

Overdischarge protection: When the battery capacity becomes low, the tool stops automatically. If the product does not operate even when the switches are operated, remove the batteries from the tool and charge them.

To prevent the switch trigger from being accidentally pulled, a lock-off button is provided.

To start the tool, depress the lock-off button and pull the switch trigger. Release the switch trigger to stop.

Do not pull the switch trigger hard without pressing in the lock-off button. This can cause switch breakage.

This tool has “high speed mode” and “high torque mode”. The tool automatically changes the operation mode depending on the work load.

When the work load is low, the tool will run in the “high speed mode” for quicker cutting operation.

When the work load is high, the tool will run in the “high torque mode” for powerful cutting operation.

The mode indicator lights up in green when the tool is running in “high torque mode”. If the tool is operated with excessive load, the mode indicator will blink in green.

Loosen the lever on the depth guide and move the base up or down. At the desired depth of cut, secure the base by tightening the lever.

For cleaner, safer cuts, set cut depth so that no more than one blade tooth projects below the workpiece. After adjusting the depth of cut, always tighten the lever securely.

Loosen the lever and set for the desired angle by tilting accordingly, then tighten the lever securely.

Positive Stopper: The positive stopper is useful for setting the designated angle quickly. Turn the positive stopper so that the arrow on it points to your desired bevel angle (22.5°/45°/56°). Loosen the lever and then tilt the tool base until it stops. The position where the tool base stops is the angle you set with the positive stopper. Tighten the lever with the tool base at this position.

For straight cuts, align the 0° position on the front of the base with your cutting line.

For 45° bevel cuts, align the 45° position with it.

To turn on the lamp without running the tool, pull the switch trigger without pressing the lock-off button.

To turn on the lamp with the tool running, press and hold the lock-off button and pull the switch trigger.

The lamp goes out 10 seconds after releasing the switch trigger. Do not look in the light or see the source of light directly.

The hook is convenient for hanging the tool temporarily. To use the hook, simply turn the hook until it snaps into the open position. When not in use, always turn the hook until it snaps into the closed position.

Always remove the battery when hanging the tool with the hook. Never hook the tool at high locations or where it may fall.

To remove the blade:

1. Press the shaft lock fully so that the circular saw blade cannot revolve.

2. Use the hex wrench to loosen the hex bolt.

3. Remove the hex bolt, ring (country specific), outer flange, and circular saw blade.

To install the blade:

1. Follow the removal procedure in reverse.

2. Be sure the circular saw blade is installed with teeth pointing up at the front of the tool.

3. Be sure to tighten the hex bolt clockwise securely. Also be careful not to tighten the bolt forcibly.

Note: For tools with an inner flange for other than a 15.88 mm hole-diameter saw blade, choose the correct side of the inner flange where the protrusion fits into the saw blade hole perfectly.

When you wish to perform clean cutting operations, connect a Makita vacuum cleaner to your tool. Connect a hose of the vacuum cleaner to the dust nozzle on the tool using the screw provided.

Hold the tool firmly. The tool is provided with both a front grip and rear handle. Use both to best grasp the tool. Set the base on the workpiece to be cut without the circular saw blade making any contact. Then turn the tool on and wait until the circular saw blade attains full speed.

Now simply move the tool forward over the workpiece surface, keeping it flat and advancing smoothly until the sawing is completed. To get clean cuts, keep your sawing line straight and your speed of advance uniform. Never force the saw. Push the saw forward at a speed so that the blade cuts without slowing.

The handy rip fence allows you to do extra-accurate straight cuts. Simply slide the rip fence up snugly against the side of the workpiece and secure it in position with the clamping screw on the front of the base. It also makes repeated cuts of uniform width possible.

Use the designated hole for the lanyard (tether strap) located near the rear battery mount area. Always keep the tool tethered when working “at height”. Maximum lanyard length is 2 m (6.5 ft). Use only with lanyards appropriate for this tool type and rated for at least 6.0 kg (13.3 lbs).

This adjustment has been made at the factory. But if it is off, you can adjust it as follows:

1. Slightly loosen the lever on the bevel scale plate.

2. Make the base perpendicular to the blade using a triangular rule or square rule by turning the adjusting bolt.

3. Tighten the lever and then make a test cut to check the verticalness.

Clean out the upper and lower guards to ensure there is no accumulated sawdust which may impede the operation of the lower guarding system. The most effective way to accomplish this cleaning is with compressed air. If the dust is being blown out of the guards be sure the proper eye and breathing protection is used.

After each use, wipe off the sawdust on the tool. Fine sawdust may come inside the tool and cause malfunction or a fire.

Never use gasoline, benzine, thinner, alcohol or the like for cleaning, as discoloration, deformation or cracks may result.
