•Fit the support flange (F) on the output shaft. Make sure that the blade is centered by fitting it to the guide on the support flange.

•Screw the support cup (E) onto the output shaft threads (CAUTION! Left-hand thread). Tighten to a torque of 35- 50 Nm (3.5-5.0 kpm). Use the socket spanner in the tool kit. Note that the locking pin (C) must remain inside the gear housing to lock the drive disk. Hold the shaft of the socket spanner as close to the blade guard/combination guard as possible.

WARNING! Tighten the lock screw (N) in the

!center hole of the support cup. Tighten to a torque of 35-50 Nm (3.5-5.0 kpm), CAUTION! Left-hand thread. If the lock screw is not fitted in the support cup, there is a risk that the support cup will come unscrewed. This means that the blade will also come loose, which could result in serious or fatal injury to the operator or others.

When loosening and tightening the saw blade nut, there is a risk of injury from the teeth of the saw blade. You should therefore always ensure that your hand is shielded by the blade guard when doing this. Always use a socket spanner with a shaft that is long enough to allow this. The arrow in the diagram shows the area where you should operate the socket spanner when loosening or tightening the nut.
