airand hand-operated grease guns are manufactured by Step Industrial Equipment Ltd. and, in addition, there is the Major-Lube lubrication set, which is suitable for use on vehicle greasing.
The grease guns range from the 300 pushon type, which has a two-stage action and can build up a pressure of 2,200 p.s.i., to the 310 side-lever type with a capacity of 1 lb. of grease and can deliver at a pressure of up to 12,000 p.s.i. In between these there are two guns—the 316 and 318—where the grease container is located at right angles to a hand piece, and the grease is pressurized by squeezing the operating lever with the fingers of the hand holding the gun. The difference between the two versions is in the capacity, one taking 0,75 lb. of grease, the other 2 lb. With both a pressure of more than 8,000 p.s.i. can be attained. The final hand gun is the 315, and this is also operated in one hand bysqueezing the operating lever towards the grease container_ When used with one hand it can deliver at more than 5,000 p.s.i.
The 315 gun is supplied as part of the equipment of the Major-Lube set, but it is specially adapted by having a connector at the bottom of the grease container to fit on a delivery outlet of a grease pump. The grease pump is hand-operated and tits into a cover suitable for 28-lb. grease tins. Completing the lubrication set is a two-wheel trolley, to which the grease tin is clamped, and on the trolley handle is a clip which carries a ReiLng pressure oil gun. Although Inc 315 is normally supplied with the Ma;orLobe, it ii also possible to have specially. adapted 316, 318 or 310 guns or an airoperated gun—the 317—instead. The 317 grease gun has its 0.75-1b. grease container mounted under the body of the gun, the airpressure connection going through the handle. Operation is by depressing a small trigger, and the air pump has a pressure ratio of 45 to I.
