Stiga 85 M manual Maintenance, Cleaning, Changing The Drive Belt, Changing Blades, English

ENGLISH GB

-keep the underside of the mower deck clean.

-use sharp blades.

-do not mow wet grass.

-mow twice (using different mowing heights) if the grass is long.

MAINTENANCE

No service action must be taken on the mower deck unless:

-the engine has been stopped.

-the ignition key has been removed.

-the spark plug cap has been removed from the spark plug.

-the parking brake is engaged.

-the mower deck is disengaged.

CLEANING

After use, rinse off the underside of the mower deck using a garden hose.

If grass cuttings have dried on to the attachment, dismantle the mower deck and scrape clean the un- derside.

If necessary touch-up the underside using a suita- ble paint to prevent corrosion.

CHANGING THE DRIVE BELT

1.Remove the mower deck from the base machine.

2.Remove the transmission casing.

3.Loosen the tension arm L (fig 8).

4.Loosen the right hand bearing box's fixing bolts M (fig 9).

5.Fit the new drive belt.

The new drive belt must be fitted so that the blades are square (90°) to each oth- er. See figure 10. If you fit the drive belt incorrectly the blades will hit each oth- er resulting in the blades being dam- aged.

6.The belt is tensioned by pushing the tension arm L forwards and then securing in position.

7.Tighten the bearing box's fixing bolts M.

When the drive belt is fitted, check, by turning the mower deck over and turn- ing the blades, that it has been fitted correctly. NOTE! The mower deck should be dismantled from the base ma-

chine.

8. Now refit the mower deck on the base machine.

CHANGING BLADES

Use protective gloves to prevent cuts when changing blades/blade tips.

Make sure the blades are always sharp. This gives the best mowing results.

Always check the blade(s) after an impact. If the blade system has been damaged the defective parts must be changed.

Always use original spare parts. Using non-original spare parts can result in the risk of damage even if they fit in the machine.

The cutting system consists of two blade bars, each with two interchangeable blade tips Y (fig 11). Both blade tips should be replaced at the same time to avoid any imbalance.

Fit the new blade tips. Tighten the screws V and W fully. Tightening torque: V - 9.8 Nm, W - 24 Nm.

And heavy impact can result in the blade tip being folded aside. Loosen the locking nut X and turn the blade tip back to its correct position. Mount a new shear bolt V. Tighten the lock nuts X and Z.
