1. SAFETY PRECAUTIONS
2. KNOWING YOUR DIESEL DISPLACEMENT PUMP
• Do not smoke or allow flames or sparks to get near fuel．
• Always refuel your engine in a well-ventilated place．
• Do not overfill the tank and always close the filler cap securely．
• Never run the pump indoors as the engine emits poisonous carbon monoxide．
• Do not touch the mufflerduring orjust after operation；as the engine and muffler get hot．Always let the
engine fully cool before touching and storing the pump indoors．
• Always keep the pump at least 1 meter (3 feet) away from buildings and other equipment during opera-
tion• • Do not place flammable objects or liquids close to the pump．
• Before operating your displacement pump，please check your local laws and requlations before operating
your pump．It is illegal in some areas to operate an engine without a spark arrester；therefore，a spark arres-
ter is available as an optional part for this pump．
• Know all the pumps controls and know how to stop the pump quickly in the event of an emergency．Do
not let anyone without proper instructions operate the pump．
• Always keep children and pets away from the pump．
• Do not pump flammable or corrosive liquids such as gasoline or acid．In order to prolong the life of your
pump，avoid pumping corrosive liquids such as seawater，chemical solutions，used oil, or acidic liquids．
• Always operate your pump on a level surface．If the pump is tilted，fuel may spill and rapid wear might
occur as a result of inadequate lubrication．

Suction Hose
The first step in preparing the pump for operation is to install the suction hose．For the suction hose，use a
reinforced-wall or wire braided hose to prevent suction collapse．A short hose is recommended over a long
hose．The pumps have standard National Pipe Threads on them；therefore，any standard hose set will fit
with the pump．If your hoses are metric threads or any other standard，please give our company a call we
carry a full line of adapters or provide you with a possible solution．
NOTE：Always install the provided strainer on the end of the suction hose before pumping If gravel or debris
enters the pump，the impeller can be seriously damaged．
Shown below is the pump hose wtilizing a barbed connection and hose clamp．If you already have speciali-
zed hose，disregard the following diagram．When using the barbed conection setup，make sure to use a
hose clamp to properly secure the hose to the barh connector
3. PRE-OPERATION PREPARATION

Discharge hose
The second step is to install the discharge hose．The discharge hose can be fabric，just make sure to use
ahose clamp to secure the hose to the barb．This will prevent the hose from disconnecting under high pressure．
Note: A short and large-diameter hose is preferred over any other．A short and large diameter will provide
lower fluid friction and improve efficiency．
Engine oil
Engine oil is an important factor in determining the performance and life of your engine．Always make sure
the oil level is within the upper and lower limits specified on the oil dipstick．Make sure to check the engine
oil on a level surface or incorrect readings will result．
•To check the engine oil，first，remove the oil dipstick by turning counterclockwise．
•Wipe the dipstick clean and insert the dipstick back into the oil filler neck．Do not screw it in．Please refer
to Fig 2-1．
•If the level is low．fill engine oil to the top of the oil filler neck with the recommended oil below．
Below is a table of recommended oil grades for the engine in various weather conditions.
Please use the proper oil according to the Table 2-1．

Note：For diesel engines，we highly recommend the use of 15W-40 engine oil．Some other
grades are comparable，but 15W-40 is the preferred oil grade．
Fuel
Remove the fuel cap and fill the fuel tank with diesel fuel．The preferred fuel for diesel engines is diesel
number 2．which can be easily obtained from a gas station.Do not use other fuels until consulting with your
local dealer or our company．
The capacity of your fuel tank is 3.3 US gallons．
Do not smoke or allow flames or sparks to get near fuel．Always refuel your engine in a wellventilated place
Do not overfill the tank and always close the filler cap securely
Air Cleaner
Before starting your displacement pump，remove your air cleaner cover and verify that the
air filter is clean and free of debris．Clean the air filter if necessary．
5

Priming water
The pump chamber should be completely filled before operating．
Note：Never operate the pump without priming water or the pump will overheat．Prolonged operation of
the pump under these dry conditions will damage and destroy the seal．
Follow these guidelines to fill the pump with priming water．

4. STARTING THE ENGINE
Recoil Starting
Note：When the engine is running，do not pull the recoil handle，otherwise the engine maybe damaged．

Diesel engine with electric starter system
Starting
The preparation of the diesel engine for the electric starting system is the same as the manual recoil type．
a. Open the fuel cock．
b. Set the speed governor lever to the start position.
c. Turn the start switch clockwise to the“Start”position．
d. If the engine is started，immediately remove your hand away from the key switch．
e. If the engine does not start after 10 seconds，wait awhile (about 15 seconds) before tying to start the
engine again．
If you run the starter motor to long，the voltage of the accumulator will drop and the motor may be damaged．
Keep the key switch in the “ON” position
Battery
a. Always check the liquid level of the battery every month，if the level is lower than the low limit mark，refill
the battery with distilled water till you reach the upper limit mark．
If the liquid level in the battery is to low，the electric starter will not function to its best potential．Always keep
the level of the liquid in the baaery between the upper and lower linits．If there is too much liquid，the liquid
will splash onto other neary parts thereby mining the battery．
Cold starting
If the engine is difficult to start in winter,take off the rubber seal plug and put 2cc of machine oil into
the hole．
Notice：Engines supplied to the Torrid Zone will not contain the rubber plug．A solid plug is provided instead．
