The wheel should turn smoothly without stiffness or detectable resistance not originating from
abrasion of brake shoes in brake drum.

Inspection and adjustment of bearings may only be conducted, when the sand spreader is
hitched to a tractor and trailer load box is empty.
Bearings replacement, lubrication and repairs connected with brake system and wheel axle
should be entrusted to specialist service provider. For axle technical service, the user may
only inspect the technical condition of the axle system, inspect bearing slack and their
adjustment.
Inspection of slack and technical condition of wheel axle bearings must be performed
after the first month of use or 100km of travel, and then every 6 months of sand spreader
use.
5.3 ADJUSTMENT OF MAIN BRAKES
Brakes adjustment is necessary when:
•
as a result of wear of brake shoe linings between lining and drum there is
excessive slack and reduced braking effectiveness.
•
wheel brakes do not brake evenly or simultaneously.
If brakes are correctly adjusted, braking of sand spreader wheels takes place simultaneously.
Brakes adjustment involves changing setting of axle shaft expander arms (1) in relation to
expander shafts (2). In order to do that loosen clamp bolts (3), dismantle expander levers and
set them in the correct direction i.e.:
•
backwards - if brake brakes too late (A)
•
forward - if brake brakes too early (B)
