WHEN SIPHONING GAS:
Follow Steps 1-4 listed on page 4. After each use, pump out the remaining residue of gas
from both the Intake Hose (2) and Discharge Hose (3). Wash thoroughly with soap and
water and let air dry before storing the Pump.
Please note: Many cars have a baffle (small metal flap) in their gas tank inlet to prevent a
siphoning tube from being inserted. Use a screwdriver (not included) to hold open the baffle
when siphoning.
TO CHANGE OIL:
1. Follow Steps 1-2 and then insert the Dipstick Connector (4) into one end of the Dipstick
Tube (7). Insert the Dipstick Connector (4) into the end of the Intake Hose (2). See Figure 2.
2. Insert the other end of the Dipstick Tube (7) into the engine dipstick hole until it reaches
the bottom of the crankcase. Place the Discharge Hose (3) into the oil drain pan and begin
to pump.
TO USE AS AIR PUMP:
1. Insert the Air Pressure Hose (6) into a Hose Connector (5) and then insert both into the
discharge nozzle (bottom valve on Pump). See Figure 3.
2. Tighten securely and begin pumping. Please note: To inflate footballs, beach balls, etc.,
place an inflation needle in the threaded adapter on the end of the Air Pressure Hose (6)
and begin pumping. Warning: Always adhere to the inflatable item’s recommended PSI
rating. Over-inflating could result in damage to item or a possible explosion and result in
serious injury.
