2.Using emergency handle, crank post clockwise by hand until fully retracted, then turn crank one turn counterclockwise.
3.Replace head on post and make sure that drive pin is engaged with post coupler. Tighten Allen set screws.
Maintenance
1.Every two years remove screws and cover and check grease condition. Use HMP grease similar to lubricate 630AA and spread on gear teeth, Grease is not required on the nylon timing gears. No internal lubrication of the post is required, but an occasional external application of a silicone or
2.Before replacing the cover ensure that the plate and limit switch unit are located correctly.
3.Apply a little sealing compound around the mating surface of the gear cover and replace screws tightening them diagonally. Check synchronization if head has been removed from the post.
4.A little penetrating oil on the Allen setscrews occasionally will help prevent corrosion and difficult removal.
Note: Leave tow vehicle transmission in neutral when lifting both units. Dolly wheels are not recommended. Always retract stabilizing jacks before using your Super Jack under load.
