Tightening the Trip Spring and Adjusting the Eye Bolt 
 

To properly adjust the Trip Springs, tighten the top locknut 4 complete rotations beyond the point that the coils begin to separate. Tighten the bottom locknut to hold eyebolt in position as shown. It is important that each eye bolt is locked in this position to work properly when the moldboard experiences tripping action.


Greasing the Pivot and Cotter Pins 
 

Use a grease gun to grease the Pivot Pins. They are provided with a grease fitting for this purpose. Also, remove and grease the cotter pins, then reinstall them to their original position. This will keep your plow angling smoothly and securely.


Maintaining Cutting Edge and Mounting Bolts 
 

Monitor the cutting edge of your plow for excessive wear and tear. Replace it as soon as it appears worn on either corner approximately 4”. Replacing the cutting edge will prevent damage to the moldboard. Also, check and retighten all mounting bolts after the first plowing session of the season and at regular intervals throughout the season.

 

Checking Oil Level


Use a standard drinking straw or popsicle stick to check your fluid level. Remove the filler cap and dip the straw into the fluid reservoir. Always check fluid level with the lift piston fully retracted. The fluid level should be 1-1/2” below the filler hole. If your fluid is low or appears excessively dirty, refer to your owners manual for instructions on filling and changing your hydraulic fluid. Only use Meyer Hydraulic M-1 Fluid.


Monitoring the Condition of Your Hoses, Couplers and Rams 
 

Check all hoses for bubbles or cuts and couplers for rust or leaks. A failure in a hose or coupler will result in a loss in oil pressure and cause power angling failure. Check rams for rust and leaks, either of these problems can introduce water into your hydraulic system which may cause freeze-ups. If you find any of these problems, replace the damaged parts with Meyer Genuine Parts available from your local distributor.
 

Monitoring the Electrical System and Battery Terminal Connections 
 

For maximum efficiency, the vehicle supporting the plow must be properly serviced. The system should consist of at least a 70amp/hr battery and a 60-amp alternator. Be sure to regularly check the battery terminals to assure that they’re clean and free of corrosion, adding dielectric grease to all connections will help prevent corrosion from occurring. Also check the electrical connections to assure they’re tight and corrosion free. Make sure that all wires are being held clear from moving or hot engine parts or from sharp sheet metal. For maximum efficiency, the battery, alternator, and regulator must be in top operating condition to assure maximum electrical output.
 

Storing the Plow and Hydraulic Unit


After you have disconnected the plow from your vehicle, extend the lift cylinder to end of the stroke and coat the lift rod with light grease. This fills the cylinder with hydraulic fluid and protects the interior and exterior from rust and corrosion. Also coat the exposed portions of the power angling cylinder rods with light grease. Be sure to reconnect the quick couplers at the Power Angling rams and plug in the weather plugs on Hydraulic Unit to keep them clean and to prevent contamination of the system. Coat all pivot pins and other wear points with chassis lubricant. Unplug all electrical connections at the power unit. Coat all connections with a dielectric compound to prevent corrosion and plug them into their corresponding weather plugs. Unplug the plow lights, tape or use dielectric compound at light connections to prevent corrosion.
 

WARNING: THE LIFT ARM EXTENDS BEYOND THE BUMPER OF THE VEHICLE. TO MINIMIZE DAMAGE IN A FRONT END COLLISION, THE LIFT ARM SHOULD BE REMOVED FROM THE VEHICLE WHEN YOUR SNOWPLOW IS REMOVED.

Meyer M-2 Hydra-Flush should be used to flush contaminants from the system. It should also be used for off-season storage.

 

Troubleshooting and Owners Manual


There is a Troubleshooting section in your owner’s manual with conditions, possible causes and corrections. There is also advice and instruction on several different topics in the owner’s manual. Meyer Products recommends that the manual be read cover to cover so that you, the consumer, are completely aware of all important safety recommendations.

 

Adjusting the Drop Speed


If you have purchased an E-58H/E-61/E-68 unit the rate at which the plow is lowered is adjustable.

 
Using an 1/2" wrench loosen the jam nut on the PA Block on the driver side or front of the unit and turn the screw clockwise to decrease the drop speed, or turn the screw counter-clockwise to increase the drop speed.

 

Adjusting the Runners


Inspect moldboard runners for wear and replace them as soon as they start to wear through. Adjust the runners to maintain cutting edge height of ½” above ground in snow plowing position. Set higher when plowing on gravel driveways.
