Makita 6836 Manual

Continuous Rating (W)

Voltage (V)

Model 6836 has been developed as an upgraded sister tool to the current 6833.

Features high rotational speed of 6,000rpm for high operation efficiency while

less pressure is required on the tool to drive screws, reducing operator fatigue.

These two main advantages will allow operator to set more screws for one day

operation with less fatigue.

ASSEMBLY

When assembling Wheel to Feeder box, engage the tooth of Wheel with the concave portion of Spur gear 16. (Fig. 9)

See Fig. 10. Assemble Dust cover to Feeder box so that the protrusion on each end of Dust cover fits in the concave

portion of Feeder box.

Important: Be sure that Dust cover is securely fit in the concave portion indicated by the gray arrow.

1. Notes to Remember When Assembling Feeder Box Section

Do the reverse of the disassembling steps. Remember the following notes.

Assemble Torsion spring 4 to Stopper as illustrated in Fig. 11.

Then install the assembly of Stopper on Feeder box so that:

1. The top of Stopper is engaged with the concave portion of Spur gear 16.
