Hydraulics

Change your hydraulic fluid annually, preferably in the fall. Fresh fluid at the start of the season prevents the condensation buildup that accumulates when fluid sits idle over the summer. This simple step protects your system from internal corrosion and pump damage, ensuring reliable performance throughout the winter.

No, mixing hydraulic fluids can trigger chemical reactions that lead to sludge, seal damage, and pump failure. To improve reliability and keep your warranty intact, use the manufacturer-recommended fluid that is approved for extreme, sub-zero conditions.

This is often caused by low fluid, air in the hydraulic lines, or a clogged filter. If checking your fluid levels doesn’t resolve the issue, please visit your local dealer for a professional inspection.

This is often caused by solenoid valve contamination or an electrical coil failure. These issues typically require professional service. Please contact your local dealer for an inspection and repair.

Inspect the fluid for a milky appearance (indicating water contamination), or the presence of metal shavings (signaling internal component wear). If you notice either, flush the system immediately and contact your dealer for an inspection.

Quick Guide:

1. Detach the hoses, lift the hydraulic unit from the headgear, and disconnect all wiring harnesses and the plow module.
2. Unscrew the electric motor, hydraulic fittings, and valve coils from assembly.
3. Carefully extract the cartridge valves from the block housing.
4. Pull the quill assembly, remove the four reservoir screws, and extract the internal magnet, pump, and filter.
5. Submerge all parts in a parts washer, using a pressurized hose to flush out every cavity within the valve block.
6. Use a compressed air blow gun to remove all moisture, ensuring the block and all individual components are completely dry.

NOTE: If contamination was found in the main unit, it is crucial to also disassemble, clean, and flush all cylinders to ensure the entire system is free of debris.
