THOR–POST DRIVERS OVERVIEW
THOR post drivers are light weight, hand-held gasoline pile drivers—that reduces working strength of
the operator and produces simple and comfortable operation. Post drivers can easily be one of the most
efficient tools you may ever use—to get large or small jobs completed quicker and with much less effort.
The design of these gas-powered post drivers have made them very portable. THOR post drivers work
with a variety of fence posts, including steel posts, t-posts, sign posts, u-channel posts, guide posts,
and grounding rods. Many of our customers employ these drivers to make quick work out of securing
tent stakes, for party tent projects.
Advantage notes: Reduces the effort of using heavy machines such as generators and air compressors.
The operating handle is rubber/plastic sponge handle which can greatly reduce the recoil force of the
driver— also installed, a two-way damping spring which adds to use comfortable.

OPERATION DESCRIPTION:
2
• The operator must wear slip-resistant safety shoes and protective clothing—including
goggles and helmet. For long-time operation, operator must wear earplugs.
• While operating the post driver, maintain balance of body—the user should stand in front
of air filter to operate the machine.
• After starting the machine, do not carry out one-handed operation.
• While lifting the machine, be careful not pull throttle switch— carry, only, in idle-speed.
• Keep non-staff away from operating area to avoid injury.
• Select the medium speed to operate pile driver.
• Keep the handle dry and clean free from greasy oil or fuel mixture.
• If operation is stopped midway, for any reason, be sure to turn off the engine.
• Before use, be sure to check fastening screws of the connector are properly tightened.
(If it’s loose, it’s necessary to tighten the screws before use).
• Pure gasoline (without two-stroke engine oil) is prohibited. Compound it according to the
recommended ration of fuel on (page 3), for use.
• Gasoline is highly flammable—important, replenish fuel in a well-ventilated environment.
During fuel filling, gasoline engine MUST be turned off.
• Do not add too much oil—the oil should not exceed the neck of oil filer of fuel tank. If fuel
spills over, wait until the fuel volatilizes completely and then start the machine.
• During work, check whether fuel tank is damaged and frequently leaking—and check the
oil lid, tighten properly.
(If damage is found, close down the operation immediately for replacement).
• Remove hazardous materials such as, oil containers, gas cans or open flame from
work area.
• While post driver is used in closed areas such as tunnels, trenches and deep groove,
take precaution to ensure air circulation is adequate, to avoid gas fume poisoning.
• Avoid quick acceleration or braking, so as not to damage the machine.
• Before transport, empty fuel tank to avoid leakage and accidental fires.
• Non-professional maintenance is prohibited—avoid disassembling post driver to avoid
structural damage of parts, shortened service life of post driver.

PREPARATION FOR USE:
3
Fuel
• Use qualified 86 Octane – unleaded gasoline or higher gasoline
(For model MS-PD1002, use a 25 to 1 Fuel Mixture)
• Add fuel in a well-ventilated place.
• Do not add too much oil. The oil should not exceed the neck of fuel tank filling port.
If fuel spills, wait until the fuel is removed or volatilizes completely and then restart
the machine.
• After refueling, tighten the lid of fuel tank.

Choke
(cold engine)
Starter
• Before starting the new post driver, press the
transparent and semi-circle fuel bubble
repeatedly until carburetor is filled with fuel
see (figure 2).
(If the engine is cool, close the air door
—open air door after starting)
• Set the machine upright according to (figure 3). Hold the upper part of the handle tightly
with one hand, while the other pulls the starter grip quickly (remember to extend cord
sufficiently). Do not let the starter grip go back freely in repeated pulling—but hold it
tightly to avoid injury.
• Start the gasoline engine and then open-air door completely. After idle operation of
5 minutes, start normal work operations.
• After the gasoline engine is started, idle engine for 5 minutes to warm up the driver.
• After warmed up, press throttle handle to the appropriate regulatory position, according
to the required impact energy.
(Note: The new gasoline post driver use should mainly be set to low or medium-speed for the
first 20 hours of operation—refrain from using maximum throttle— this will extend the
service life).
• Operating speed of gasoline engine is best at medium speed.
• High-speed operation of post driver during non-piling is prohibited.

Stop
Switch
‘Stop’
• Release throttle handle and maintain idle
running of the engine for 3-5 minutes.
• Pull stop switch to the position of off/
flame-out. See the position of stop switch in
(figure 3).
Air Filter
• Check air filter regularly. Soot deposit blocking filter element of air filter will reduce power
of gasoline engine and service life. If the filter has too much soot deposit, clean it with warm
water and detergent, and then wipe dry it with dry cloth, and then install the air filter. Filter
should be replaced if damaged. In dirty environs, maintenance cycle should be shortened.
Fuel filter
• If the fuel filter is blocked, pile driver will have reduced speed and weaker impact energy.
Cleaning:Open the tank lid—remove the fuel filter from fuel tank with metal hook and clean
it. When cleaning the fuel filter, clean the fuel tank at same time— (see figure 4, 5 and 6).
Figure 3.
Figure 4. Figure 5. Figure 6.

TECHNICAL MAINTENANCE:

Carburetor
• Fuel tank and carburetor generally have
residual oil.
After some time, the residual oil will become
greasy oil which block up the oil line, prevent-
ing the engine from starting. Therefore, when
the post driver is not used for more than one
week— completely take the fuel out.
• Method: Pull out the oil inlet pipe, press
rubber bubble of fuel bubble of carburetor
repeatedly for oil discharge, and press the oil
inlet pipe back to its position when fuel in fuel
bubble and oil return pipe is emptied.
Spark Plug
To ensure normal operation of the engine,
spark plug gap must be proper. Remove
sediment with a wire brush.
See (figure 7).
Muffler
• Regularly remove dirt on inlet and outlet of muffler, or clean dirt in it with detergent.
Gearbox Lubrication
• Open the cover of the gear boxes, and lubricate the driving gear regularly with
lubricating oil to guarantee full lubrication of the gear.
Figure 7.

TECHNICAL MAINTENANCE:

The Cylinder Heat Sink
• Regularly remove dust to ensure the cylinder cooling. The gasoline post driver is
air-cooling type. If dust accumulates on the cylinder heat sink, the cooling effect will be
influenced directly, which will lead to failure of the cylinder.
Filling of Impact Cylinder Lubrication
• After working for an accumulated 50 hours, fill special lubrication (50g) for the impact
cylinder. See (figure 8, 9, and 10).
