Jiffy-Drill units may be mounted in any position. However, if they are to be mounted with switch cover down, two 1/8" diameter holes should be drilled in the cover, one at each end, to allow drainage of any hydraulic oil which might leak past the shaft seal in the hydraulic motor. If any drainage is noticed, a new shaft seal kit for the motor should be ordered. Like all seals on hydraulic equipment, the motor shaft seal may have to be replaced after extended service. Instructions for replacing the motor shaft seal are included with the seal kit.
To hold the Jiffy-Drill securely, four mounting holes are provided. Mounting bolts, 1/2"-13, should be used, and should be long enough to engage the Jiffy-Drill body to a depth of 5/8" for the rear mounting bolts and 3/8"e; in the front. Damage can occur to the unit if the front bolts engage the Jiffy-Drill body beyond a depth of 1/2". A 5/8" cross key alignment groove, 5/8" wide and 3/32" deep is provided in the base of the Jiffy-Drill body. With this groove, the Jiffy-Drill can be accurately realigned with the work after having been removed for use elsewhere.
