The new STIHL FC 95 power edger with a 4-MIX®
engine extends the range of professional and semi-
professional edgers.
The 4-MIX® engine incorporates STIHL’s patented
system of lubrication and operates according to the
four-stroke principle. It uses the same fuel mix as
STIHL two-stroke engines.
The engine has a displacement of 1.73 cu in
(28.4 cm3) and a power output of 1.3 bhp (0.95 kW).
The range of applications is the same as for model
FC 110.

1. Technical Description 1.3 Gearbox and Deflector
1.1 STIHL 4-MIX® Engine 4
The 4-MIX® engine features gas-oil lubrication.
Compared to a conventional four-stroke engine, the
4-MIX® engine has no separate oil supply in the
crankcase. Engine lubrication is provided by the fuel
mixture of gasoline and 2-cycle engine oil. 4
The benefits of this new concept are:
. Same familiar fuel mix as for STIHL two-stroke
engines
1
. Favorable fuel consumption
. Operates in all positions
. Good acceleration
. Compact construction – attractive design
245TI001 KN
. Favorable power-to-weight ratio 3 2 1
. Simple maintenance – service-friendly
. Deflector with wide skirt (1) for both sides.
. Automatic decompression system
. Double wear protection for gearbox provided by
wheel (2) and guard (3).
1.2 Tank Cap . Edging guide (4) on deflector.
The tank cap is designed for quick and simple
opening and closing.
