Electrical System Frequently problems develop due to an undersized electrical charging and storage system. Generally, the heavier the usage, the heavier the system should be. For heavy usage and in the case where a number of other devices are run off the battery simultaneously, heavier ratings are strongly recommended.

Directional Valves The M3493 circuit contains 4 directional valves identified as ‘A’, ‘B’, ‘C’ and ‘D’. Valves ‘A’, ‘C’ and ‘D’ are 3 way, 2 position spool valves. Valve ‘B’ is a 2 way, 2 position normally closed poppet valve. A basic directional valve consists of a valve cartridge and a coil.

Crossover relief valve The crossover relief valves are provided to protect the valves and manifold from the pressure spikes created when the plow strikes an object. The crossover relief valves are similar in construction to a regular direct acting relief valve. Cross over valves when activated bleeds fluid from C1 to C2 or vice versa.

-Clean all parts thoroughly before assembly and lubricate with clean oil. -Do not use Teflon tape on hydraulic connections as it can easily jam the valves and plug the filters in the system, use pipe sealant. Never apply pipe sealant at the end of fitting, always 2- 3 threads back. -X-over pressure could be set using hand (hydraulic) pump.

In order for the customer to be eligible for warranty every year, the snowplow, inclusive of all components, must be returned to an authorized Arctic dealer every spring for preventative maintenance. Warranty work must be performed by an authorized Arctic dealer. Failure to do so will nullify any future warranty claims.

Post season maintenance -Inspect the plow assembly (the blade, A-frame, lift frame, spreader bar and mounting kit, all fasteners, pins, retainers, nuts and bolts for tightness) for any damage (cracks, abnormal wear, etc.) and repair or replace part as necessary. Tighten all undercarriage bolts. Apply grease to the centre pin (if applicable).
NOTE: All Arctic snowplows have a stop built in, to prevent the blade from contacting the bottom of the bumper. If the blade is pushed too high on the snow bank, the stop will bind and cause the truck’s weight to be supported by the plow.
