1.0 INTRODUCTION

Founded by engineer George M. Pfundt in 1936, GMP started opera­tions in a downtown Philadelphia building as a specialty machine
shop doing work for the local Bell Telephone company and for the
electric utility company. GMP expanded to a production shop after
landing a contract with Western
Electric Company and, subse­quently, forming a close relation­ship with Bell Telephone Labora-

tories in Murray Hill, N.J., which
enabled it to manufacture prototypes of products for experimen­tal use within the Bell System.

Having outgrown the original factory building, the company built
a 100,000 square foot plant in Trevose, PA (a Philadelphia sub­urb) and moved there in 1957. Today GMP is recognized as a
premier worldwide supplier of specialty tools and equipment for
the outside plant marketplace. The company's products are known for their robust design and dura­bility to withstand many years of frequent use.

4.0 MAINTENANCE

This equipment has been designed to provide a long and useful life providing certain precautionary meas­ures are taken.

Before putting into service the first time, check that all parts are present and assembled correctly.
Before using, check that the brake drum and brake band is clean and free from oil, dirt or other contami-

nants. Check that the hydraulic jacks operate smoothly. Check the condition of all retaining pins and ‘R’
clips, replace if damaged.

When finished using, wipe the paint-work down with an oiled cloth. Lightly grease the pivot points with
general-purpose medium grease. Ensure that the hydraulic jacks are lowered as far as possible and apply
a thin layer of grease around the joint between piston and body. Store in clean dry conditions.

If this equipment is left outside for any extended period of time, protect against atmospheric corrosion by
applying grease to unprotected surfaces. This applies in particular to the hydraulic jack piston if it is left
extended.
