HYDRAULIC FEED TABLE
Machines equipped with a hydraulic feed table (VH models) have a pumping unit in the base. The system has an adjustable relief valve, which is factory preset at 400 p.s.i. This setting may be reduced to afford greater sensitivity for cutting soft or thin materials. Pressures may be lowered by turning the square nut located on the top right hand side of the reservoir. (See below graphic) The systems oil level must be checked periodically to assure the oil levels are maintained at the full level of the sight glass.
The feed table regulator will provide a smooth movement to the table. If the feed appears to be intermittent it is probably due to air in the system. This is normally exhausted by running the table in and out a few times.
