WARNING: Over tightening is one of the major causes for oil leaks.
Test the hydraulic controls in order to make sure that they coordinate with the movement of the broom. If they do not match, reconnect the hoses in the right order.
Connect hoses to hydraulic system
IMPORTANT: If manipulating the hydraulic controls do not create any movement, it may be, that one hose from the hydraulic lift system is interchanged with one hose from the angulation system.
NOTE: Use a coloured tie wrap (not supplied) to identify the different hoses to simplify future installation.
Activate the lifting and angling system of the accessory a few times to verify that the hydraulic cylinders and the hoses are filled with oil and the air has been purged.

10 MAINTENANCEOPERATION
AJUSTING PRESSURE OF BROOM ON THE GROUND: By turning the adjustment handle (item 1) clockwise, the pressure of the brush on the ground increases. When turning the adjustment handle counter clockwise, the pressure of the brush on the ground decreases. IMPORTANT: Frequently adjust pressure to compensate on the wear of the broom. Always use brush with the tips of the bristles like a broom and not with the sides of the bristles like a mop. Too much pressure could reduce 95% of the broom’s lifespan.
Adjust pressure on broom
GENERAL SWEEPING Minimize dust by reducing brush speed and by Never sweep with the sides Sweep with the tips sweeping after a rainfall or on a day with high of bristles Do not mop moisture.
SNOW SWEEPING The brooms works very well for slight snow removal. Decrease pressure (light pressure) on the broom for snow removal. Too much pressure = Flick action Sweep with the wind blowing in the direction of broom Shortens brush life debris (wind in your back). NOTE: Foreign objects in the snow may be thrown faster than the snow itself. DANGER Frequently clear the snow and ice accumulation from PREVENTING INJURY: the top and bottom of the broom’s hood. Take note of the danger zone when starting, operating or adjusting pressure on broom. LAWN DETHATCHING AND LEAF RAKING Certain objects may be projected as far as 10m NOTE: It is recommended to use the optional side (33’) from the accessory. wheel support kit when used for dethatching uneven Stop the vehicle ground. Apply parking brake Lower the brush onto a hard surface and adjust the height of the brush at 1’’ from the ground by turning the adjustment handle clockwise. The brush is supported by the pivoting wheels (the ground must be able to support the weight of the broom) This adjustment is usually satisfactory. Although, you may raise or lower the broom depending on the height of your grass. Low brush speed is best for lawn dethatching and leaf raking.
