Safety Precautions - OTC 4277 Manual Del Usuario

The OTC 4277 50 gpm Hydraulic Flow Meter provides the ideal solution for servicing and
commissioning hydraulic circuits on agricultural and other mobile machinery.
The kit comprises of a direct-acting flow indicator with built-in thermometer, a loading valve
and a pressure gauge all built into a strong steel case with a removable lid. The unit is self-
contained and requires no electrical power. The dials are clear and easy to read.
Installation is extremely simple and the test kit can be connected into either the pressure or
return lines. The loading valve and pressure gauge allow smooth, progressive build-up of
system pressure.
The test kit provides the service engineer with quick, accurate and simple performance testing
of pumps, motors, valves, cylinders, hydraulic tools and complete hydraulic circuits.
