2. Turvallisuustiedot
Noudata aina seuraavia turvaohjeita käsityökaluja käyttäessäsi:
- Wear appropriate personal protective equipment, including safety glasses, to protect against flying debris.
- Ensure the correct size socket or bit is used for the fastener to prevent damage to the tool or fastener.
- Do not use damaged or worn tools. Inspect all components before each use.
- Avoid using extension handles or "cheater bars" on ratchets unless specifically designed for such use, as this can overload the tool and cause breakage.
- Pidä työkalut puhtaina ja vapaina rasvasta tai öljystä, jotta niistä saa tukevan otteen.

5. Käyttöohjeet
This section details the proper use of the various components within your YATO socket set.
5.1. Using Ratchets and Sockets

Figure 5: Assortment of sockets and bits.
- Valitse oikea pistoke: Choose a socket that precisely fits the fastener (nut or bolt head). Using an incorrect size can strip the fastener or damage the tool or fastener.
- Kiinnitä räikkämekanismiin: Press the socket firmly onto the square drive of the ratchet. Ensure it clicks securely into place.
- Suuntaohjaus: Use the lever on the ratchet head to select the desired direction (tighten or loosen).
- Käytä voimaa: Place the socket squarely onto the fastener. Apply steady, controlled force to the ratchet handle. The 72-teeth ratchet gear allows for a minimum working stroke of 5 degrees, ideal for confined spaces.
- AS-DRIVE System: YATO sockets feature the AS-DRIVE system, which increases maximum torque by 25% while protecting the corners of the fastener. This system applies force to the flats of the fastener rather than the corners, reducing the risk of rounding.
- Irrota pistorasia: Press the quick-release button on the ratchet head (if present) and pull the socket off.
5.2. Using Extension Bars and Universal Joints
- Jatkovarret: Use extension bars to reach fasteners in deep or obstructed areas. Attach the extension bar to the ratchet, then the socket to the extension bar.
- Kardaaninivel: The universal joint allows for angular access to fasteners that are not in a direct line with the ratchet. Attach it between the ratchet and the socket or extension bar. Note that using a universal joint may reduce the effective torque and should be used with care.
5.3. Using Screwdriver Bits and Spinner Handle
- Bitin valinta: Choose the appropriate screwdriver bit (Slotted, Phillips, Pozidrive, Torx, Hex, Square) for the screw head.
- Spinner Handle: Insert the selected bit into the bit holder on the spinner handle. This is suitable for fasteners requiring less torque or for quick turning.
- Ratcheting with Bits: For higher torque applications, use a bit adapter (if included or separately acquired) with the 1/4-inch ratchet.
6. Huolto
Proper maintenance ensures the longevity and reliable performance of your YATO socket set.
- Puhdistus: Pyyhi kaikki työkalut jokaisen käyttökerran jälkeen puhtaalla, kuivalla liinalla lian, rasvan ja roskien poistamiseksi. Pinttyneeseen likaan voi käyttää mietoa rasvanpoistoainetta, minkä jälkeen kuivaa huolellisesti.
- Voitelu: Periodically, apply a small amount of light machine oil to the ratchet mechanism to ensure smooth operation. Do not over-lubricate.
- Tarkastus: Regularly inspect sockets for cracks, wear, or rounding of the drive square. Check ratchets for smooth operation and ensure the direction lever functions correctly. Replace any damaged components immediately.
- Varastointi: Always return tools to their designated slots in the carrying case after use. Close and latch the case securely. Store the case in a dry environment, away from excessive humidity or extreme temperatures, to prevent corrosion.
