Genuine Chip Flap for your 090 070 saw, these are high quality and last well. Oil tank guards and screws are available too.

This is a part that will last many years without failing, IMO it's a pretty necessary part to have for operator comfort yet it seems to be missing off just about every 070, 090 I ever see.

 

One tip too... when you place the saw down after fitting the chip flap, pull the flap forward. This way after a few day the flap will develop a "memory" and will always sit forward when the saw is sitting on its base; this creates the correct curve to better catch and deflect the chips.
