4. Especificacions

5. Configuració

This section covers the basic setup for using your Makita DTD173/TD173D Impact Driver. If you are replacing components, refer to the exploded diagram (Figure 3.4) for guidance.

5.1 Instal·lació de la bateria

1. Assegureu-vos que el tornavís d'impacte estigui apagat.
2. Align the battery pack with the battery interface board slot on the tool.
3. Slide the battery pack into the slot until it clicks securely into place.
4. Per treure-la, premeu el botó d'alliberament de la bateria i feu-la lliscar cap a fora.

Instal·lació d'5.2 bits

1. Pull the chuck sleeve forward to open the chuck.
2. Inseriu la broca hexagonal de 1/4" desitjada al mandril.
3. Release the chuck sleeve. The bit should be securely locked in place. Pull on the bit to ensure it is properly seated.

6. Instruccions de funcionament

Follow these general guidelines for operating your impact driver.

6.1 Engegada/apagada

• To turn on, pull the trigger switch. The tool speed increases with trigger pressure.
• Per apagar, deixeu anar el disparador.

6.2 Rotació endavant/enrere

• L'interruptor d'avanç/retrocés es troba a sobre del gallet.
• Push the switch from the left side for forward rotation (tightening).
• Push the switch from the right side for reverse rotation (loosening).
• Ensure the switch is in the center position to lock the trigger and prevent accidental startup.

6.3 Conducció d'impacte

• Position the bit firmly against the fastener.
• Apply steady pressure and pull the trigger. The impact mechanism will engage automatically when resistance is met.
• Do not over-tighten fasteners.

7. Manteniment

Un manteniment regular garanteix la longevitat i el rendiment òptim del vostre atornillador d'impacte.

7.1 Neteja

• Desconnecteu sempre la bateria abans de netejar-la.
• Netegeu el cos de l'eina amb un drap suauamp tela. No utilitzeu productes químics aggressivs ni netejadors abrasius.
• Mantingueu les obertures de ventilació netes de pols i deixalles per evitar el sobreescalfament.
• Netegeu el mandril regularment per assegurar canvis de broca suaus.

7.2 Emmagatzematge

• Guardeu l'eina en un lloc sec i segur, fora de l'abast dels nens.
