It may be necessary to drill out the holes in the Trimmy Fix to make it easier to fit the
trimmer cords.
11.Cut the trimmer cords to correct length (measured from the outer edge of the Trimmy
Fix):
225: 145 mm (5.7 inches)
232: 155 mm (6.1 inches)
235: 170 mm (6.7 inches)
Fit the Trimmy Fix on the machine. Note! For 235 the splash guard must be removed.
Bear in mind the trimmer cords.
12.Start the engine.
13.Apply full throttle. Use a narrow blade screwdriver, inserted through the hole in the cap
until it reaches the slot in the needle (max. blade width 2 mm, 0.08 inch) to turn the H-
needle counterclockwise until the engine clearly 4-cycles. Turn the H-needle back
clockwise until the 4-cycling stops and a top speed of 8400 +- 200 rpm is achieved.
Note that the revolution 8400 +- 200 shall be achieved as close to the 4-cycle limit as
possible.
14.Let the engine run for 2-3 minutes until warm.
15.Check that the top speed is still 8400 +- 200 rpm. Adjust if necessary.
16.Check that the locking cap is still adjusted to its richest setting. (Turned
counterclockwise to stop.)
17.Gently knock the locking cap into position. Use a 5 mm (0.2 inch) mandrel or the
locking pin for the gear, 502 02 61-03.
This is a basic carburettor adjustment. Further fine adjustments, within the limits the
locking cap allows, may be necessary to achieve optimum performance. See the
Operator’s manual.
