F510 & F525 – CHOKE PLATE CHECK

Reason:
To make sure the choke plate is fully closed when the throttle lever is in the full choke position.
Procedure:
IMPORTANT: Check and adjust throttle cable before adjusting choke, to ensure accurate choke adjustment.
1. Check and adjust throttle cable.
2. Move throttle control lever to full choke position.
3. Try to move choke rod (A) toward carburetor (in direction of arrow). Choke rod should NOT move. If choke rod moves in direction of arrow, the choke plate is not fully closed.
4. Move throttle lever to fast idle position.
5. Check holes (E) in control panel (F) and throttle arm (D). They MUST BE in visual alignment. Check for gap between screw (B) and choke arm (C). Gap should be approximately 0.25—3 mm (0.01—0.12 in.).
6. Try to move choke rod (A) toward control panel (arrow). Choke rod should NOT move. If choke rod moves in direction of arrow, the choke plate is not fully open.
Results:
• If choke rod DOES NOT move in either direction with throttle control lever in specific positions, choke operation is OK.
• If choke rod MOVES in either direction with throttle control lever in the specific positions, perform Choke Plate Adjustment procedure.

F510 & F525 – THROTTLE CABLE ADJUSTMENT

Reason:
To make sure the throttle control lever contacts the slow idle stop at slow idle.
Equipment:
• 6 mm (15/64-in.) Drill Bit or 45M7036 Pin
Procedure:
1. Move key switch to OFF position.
2. Put transaxle/transmission in neutral.
3. Engage park brake.
4. Raise and lock seat platform.
5. Raise rear shroud.
6. Move throttle lever to fast idle position.
7. Align hole in throttle control lever (A) with hole in throttle control plate (B). Put a 6 mm (15/64-in.) drill bit (C) or 45M7036 Pin through holes to keep the throttle control lever from moving. Be sure drill bit or pin is perpendicular to the throttle control plate.
8. Loosen cap screw (D) and pull throttle cable tight. Tighten cap screw.
9. Remove drill bit or pin.
10. For F510 (S.N. 100204— ) and F525 (S.N. 100393— ) only, move throttle lever to the slow idle position. Be sure the throttle control lever screw contacts the throttle control plate before the throttle lever bottoms out.
11. Move throttle lever through full range to be sure linkage is not binding.

F510 & F525 – ENGINE USES TOO MUCH OIL

NOTE: 1. Oil consumption is too high if the oil level
moves from full to add in less than 18 hours.
2. Oil level should always be checked after
the engine has been run long enough to
warm the oil. If the oil is checked cold then
rechecked after warm up it is normal for the
oil level to raise as much as 2 mm (0.08 in.)
on the dipstick because of expansion.

Conditions:
• Transmission in neutral
• Park brake engaged
• PTO disengaged
