Engine exhaust gases contain poisonous carbon monoxide. This gas is colorless and odorless, and can cause death if inhaled. NEVER operate this equipment in a confined area or enclosed structure that does not provide ample free flow air.
DANGER - Explosive Fuel Hazards
Gasoline is extremely flammable, and
its vapors can cause an explosion if ignited. DO NOT start the engine near spilled fuel or combustible fluids.
DO NOT fill the fuel tank while the engine is running or hot. DO NOT overfill tank, since spilled fuel could ignite if it comes into contact with hot engine parts or sparks from the ignition system. Store fuel in approved containers, in well-ventilated areas and away from sparks and flames.

MQ-D305/D306 SERIES DIAPHRAGM PUMP S— PARTS MANUAL— REV. #2 (08/24/05) — PAGE 11
MQ-D305/D306 SERIES— GENERAL INFORMATION
APPLICATION
MQ Model D305BR/D306H series diaphragm
The
pumps are designed to be used for de-watering applications. The suction and discharge ports on this pump
use a 3-inch diameter opening, which allows the pump to pump at rate of approximately 5,100 gallons/hour (gph) or 19,305 liters/hour (lph).
Diaphragm pumps use a positive displacement design rather than centrifugal force to move water through the casing. This means the pump will deliver a specific amount of flow per stroke, revolution or cycle. These pumps are commonly referred to as mud hogs, mud hens and mud suckers. Their names reflect their
Elevation
Higher elevations will effect the performance of the pump. Due to less atmospheric pressure at higher altitudes, pumps DO NOT have the priming ability that they have at sea level. This is due to the “thinner air” or lack of oxygen at higher altitudes.
A general rule of thumb is that for every 1,000 feet of elevation above sea level a pump will lose one foot of priming ability.
For example, in Flagstaff, Arizona where the elevation is approximately 7,000 feet, the pump would have a suction lift of only 18 feet rather than the 25 feet at sea level. Table 3 shows suction lift at various elevations.

Suction Lift
This pump is intended to be used for dewatering applications and is capable of suction lifts up to 25 feet at sea level. For optimal suction lift performance keep the suction hose or line as short as possible. In general always place the pump as close to the water as possible.
Pump Support
The pump should always be placed on

Figure 2 shows a typical application using the MQ D305/D306 series diaphragm pump. Please note that this pump is intended for the removal of clean water and water containing some debris and solids. Maximum size of solids should not exceed 1.5 inch (38 mm) in diameter. DO NOT set strainer on bottom of water bed. Placing the strainer above the water bed will prevent the pump from drawing in excessive amounts of sand and foreign debris.

Figure 2. MQ-D305/D306 Series Pump Application
1. Pump – The MQ D305/D306 series are 3-inch diaphragm pumps and are used in general de-watering applications. Typical dewatering applications consist of cleaning out cesspools and septic tanks, draining slow seepage from small excavations, trenches and construction sites, or pumping out industrial waste.
6. Suction Port – Connect a 3-inch inlet hose to this port.
2. Fill Cap – Prior to operation, the pump casing should be filled with water. Remove this cap to add water to the pump.
7. Suction Hose – Connect a flexible rubber hose to the

6. Choke Lever – Used in the starting of a cold engine, or in cold weather conditions. The choke enriches the fuel mixture.
7. Air Cleaner – Prevents dirt and other debris from entering the fuel system. Remove wing-nut on top of air filter cannister to gain access to filter element.
NOTE
8. Spark Plug – Provides spark to the ignition system. Set spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch) Clean spark plug once a week.
9. Muffler – Used to reduce noise and emissions.
CAUTION - Burn Hazard
Engine components can generate extreme heat. To prevent burns, DO NOT touch these areas while the engine is running or immediately after operating. NEVER operate the engine with the muffler removed.
5. Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop the flow of fuel.
10. Fuel Tank – Holds unleaded gasoline. For additional information refer to engine owner's manual.
Honda Engine Shown
Operating the engine without an air filter, with a damaged air filter, or a filter in need of replacement will allow dirt to enter the engine, causing rapid engine wear.

CAUTION - Read Manual
Please read the entire maintenance section in this manual before servicing the pump. In addition for operator safety, please read all safey messages at the begining of the manual
Inspection
1. Clean the pump, removing dirt and dust, particularly the engine cooling air inlet, carburetor and air cleaner.
2. Check the air filter for dirt and dust. If air filter is dirty, replace air filter with a new one as required.
3. Check carburetor for external dirt and dust. Clean with dry compressed air.
4. Check fastening nuts and bolts for tightness.
Engine Oil Check
1. To check the engine oil level, place the pump on secure level ground with the engine stopped.
2. Remove the filler dipstick from the engine oil filler hole (Figure 4) and wipe clean.
Motor fuels are highly flammable and can be dangerous if mishandled. DO NOT smoke while refueling.

Maintenance
Perform the engine maintenance procedures as indicated below:
DAILY
■
Thoroughly remove dirt and oil from the engine and control area. Clean or replace the air cleaner elements as necessary. Check and retighten all fasteners as necessary. Check the spring box and bellows for oil leaks. Repair or replace as needed.
WEEKLY
■
Remove the fuel filter cap and clean the inside of the fuel tank.
■
Remove or clean the filter at the bottom of the tank.
■
Remove and clean the spark plug (Figure 20), then adjust the spark gap to 0.028 ~0.031 inch (0.6~0.7 mm). This unit has electronic ignition, which requires no adjustments.

PREPARATION FOR LONG -TERM STORAGE
Pump Storage
For storage of the pump for over 30 days, the following is required:
z
Drain the fuel tank completely.
z
Run the engine until the fuel is completely consumed.
z
Completely drain used oil from the engine crankcase and fill with fresh clean oil, then follow the procedures described in the engine manual for engine storage.
z
Remove the pump cover and clean inside of pump housing. Coat inside of pump housing with a light film of oil to reduce corrosion. A spray can of oil works well for this application.
z
Cover suction and discharge ports with duct tape to prevent any foreign matter from falling into pump.
z
Cover pump and engine with plastic covering or equivalent and store in a clean, dry place.
z
To protect the water cooled-seals, place one-half pint of lubricating oil (new or used) through the discharge opening on the pump and crank the engine several times. This will prevent excessive corrosion and also keep the mechanical seal lubricated.
