TABELA 8.3 - RECOMMENDED SPEED AND DRILL BITS FOR DIFFERENT MATERIALS FOR MODEL 13.
5.11. Adjusting the belt tension:
• To verify the belt tension, apply a 10 pound (3,7 kg) force, or manual force on the belt.
• The deflection should be 1/2" (x = 12,5mm) + 10% (Figures 8.15 and 8.16).

5.12. Electric motor:
• For the product that comes with motor from the factory, the drill is supplied with an 110V or 220V electric
motor (single voltage).
• When operating in places with a voltage different from the indicated, use a voltage transformer (not supplied
with the product). Check the alignment of the pulleys and the belt tension before the first use (Figures 8.15
and 8.16).
5.13. Adjusting the spindle spring:
• Move the lock nuts to the lowest position, and lock them in this position with a tool. This will prevent the
spindle from falling when actuated by the spring (Figure 8.17).
• Place the screw driver in the lower front slit (A) on the spring cover (B), and keep it in this position while
loosening and removing the nuts.
• Turn the screwdriver anti-clockwise carefully and fit the next slit.
• Tighten the lower nut (C) with the tool.
• To increase tension on the spring: Move the lock nuts to the highest position and check the tension while
moving the handle.If there's not enough tension on the spring, repeat the steps above.
• Check the spindle when moving the handle. The movement of the spindle must be smooth, without restricted
movements. If the movement is too tight, loosen the nuts so that it moves without difficulty (Figure 8.17).
Note: Wear protective gloves when performing this adjustment.
