INSTRUCTIONS
DIESEL TESTER
MODEL
DT-1300
IMPORTANT: Prior to putting this new tester into use, familiarize yourself with the following instructions.
Since the tester is capable of developing very high pressures, improper use could result in
damage to instrument or injury to operator.
1. Thread HANDLE (Item 11) into CAM (Item 10).
2. PUMP VALVE (Item 19)
a. Turning valve clockwise until it seats shuts the tester off, giving a true leakage reading of the
device being tested.
b. Turn valve two or three turns counter-clockwise off its seat for normal pump operation.
3. GAGE VALVE (Item 20)
a. To apply pressure to a device without overloading gage, turn the valve clockwise until it seats. This
position is used to protect gage from hydraulic shock.
b. To test any device, using the gage, turn valve counter-clockwise to a neutral position, approximately
one turn off its seat.
c. To release pressure on the test system. continue turning gage valve counter-clockwise until pressure
is released. Screw valve in (c1ockwise)again in preparation for the next test.
4. CAUTION: Continuous testing in the upper 1/5 of gauge scale and
severe hydraulic shocks without gage
valve closed could result in reduced gage life. Avoid when possible.
5. QUICK-CHANGE GAGE (Item 21)
Before interchanging gages, release existing pressure on gage to avoid damage to instrument. Place
fingers in semicircular opening under gage housing and push Gage (Item 21) and Adapter Assembly (Item 22)
up and out. To install another gage, merely reverse procedure, pressing gage in from the top.

6. PUMP OUTPUT CAPACITY - 1300mm (1.3 cc) per stroke at 7500 psi.
7. FILTER (Item 4)
The tester is equipped with a very fine (3 to 5 Microns) filter which will remove any dirt that may be in the
fluid. The use of clean fluid will insure longer service and life of filter.
8. FILLER PLUG (Item 15) must be left loose while tester is in operation to allow air to enter fluid re-
servoir.
9. Before transporting, close pump and gage valves and filler plug to avoid leakage.
10. Remove filler plug (Item 15) and fill with fluid desired for testing. Reservoir capacity - Approximately
1/2 gallon.
11. Operate pump handle until air is purged from the system as evidenced by fluid emitting from discharge
connection (Item 35). This step is also necessary in the event the tester runs completely out of fluid.
12. IMPORTANT: When-dealing with high pressures and precision parts the introduction of dirt is very harm-
ful. Be sure all connecting apparatuses are clean before attachment to device to be tested. The simplest
and best way to do this is to pump fluid through them with the tester.
13. CAM (Item 10) surface and DOWEL (Item 9) should be lubricated every 10 to 20 hours of tester use.
14. Keeping above instructions in mind will assure trouble free operation and efficient service in a wide
variety of tests.
