Power Post Driver Overview

Filling with Gasoline and Oil

ADD OIL BEFORE STARTING THE ENGINE
The Power Post Driver is shipped without fluids installed.
Keep the caps on the fuel and oil fills until you are ready to pour either gasoline or oil into the correct fill.

1. Place the machine on a level surface, add some SAE 10-30W engine oil into the oil fill and wait one minute for the oil to settle, then continue filling with oil.
2. Check the dipstick and continue adding oil a little at a time, rechecking the dipstick until the oil reaches the fill mark. Be careful not to overfill.
3. Fill the fuel tank with fresh, unleaded gas (min. 85 Octane), to 1/4” from the top of the fill neck to allow for expansion. Be careful not to over fill and reinstall the cap before starting.

ALWAYS FILL THE TANK WITH ENGINE OFF AND COOL.
ALWAYS CHECK THE OIL LEVEL BEFORE OPERATING.
Allow the engine to cool for at least two minutes before removing the fuel cap.
Before performing any adjustments to the Power Post Driver or any maintenance, stop the engine, wait five minutes to allow parts to cool.

Starting the Engine

1. To start a COLD engine, move the choke lever upwards to the CLOSED position (see Figure 1). Lock the throttle by depressing the trigger and while the trigger is depressed, push in the button next to the thumb switch. Hold the button in and release the trigger. The throttle is now in the high idle position (see Figure 2).
2. To start a WARM engine, move the choke lever downwards to the OPEN position and do not lock the throttle into the high idle position.
3. Press the priming bulb repeatedly until fuel can be seen in the clear-plastic fuel return tube (see Figure 1).
4. Slide the engine ON/OFF switch on throttle handle down or into the ON position. Grasp the recoil starter handle and pull lightly until you feel resistance, then pull quickly towards you and return the recoil starter slowly. To prevent damage to the starter, do not allow the recoil starter cord to snap back against the engine.
5. If the choke lever was moved to the CLOSED position to start the engine, gradually move it to the open position as the engine warms up. As the engine warms up also release the high idle lock slightly depressing the trigger and then immediately releasing it. Use caution as to not engage the clutch.

TO PREVENT PERSONAL INJURY OR DAMAGE TO THE POST DRIVER TURN THE ENGINE TO THE OFF POSITION BEFORE FOLLOWING THE RESTARTING A HOT ENGINE PROCEDURE
Restarting a Hot Engine
If the engine is operated at high ambient temperature, then turned off and allowed to sit for a short period, it may not restart on the first pull of the recoil starter. Follow the following

1. Turn the engine switch to the OFF (see Figure 2).
2. Move the choke lever to the OPEN position (see Figure 1).
3. Hold the throttle trigger in the MAX speed position.
4. Pull the recoil starter handle 3 to 5 times.
5. Follow the Starting the Engine instructions above with the choke lever in the OPEN position.

Operation

Driving a T-Post

1. Have an assistant hold the t-post in the desired horizontal position or manually drive the t-post into the ground a short distance, so that it is free standing upright.

2. With the engine running, position the post driver over the top of the t-post, gripping the handles firmly (see Figure 3).

3. The Power Post Driver should be positioned at the same angle as the t-post that it will be driving (see Figure 4).

4. Apply steady downward pressure to the handles while depressing the throttle trigger slightly to engage the clutch and hammer.

5. Once you are confident that the post is driving into the ground straightly, depress the throttle trigger fully to operate at maximum speed until the post is driven to the desired depth.
   NOTE: Using a level will help ensure driving the post into the ground at a perpendicular angle.

6. Release the throttle trigger dropping the engine RPM back to idle before removing from the post.

7. When the engine has returned to idle, proceed to the next post repeating the steps outlined above.

Maintenance

BEFORE PERFORMING ANY MAINTENANCE PROCEDURE STOP THE ENGINE, WAIT FIVE ¤5¥ MINUTES TO ALLOW ALL PARTS TO COOL.
Regular maintenance is the way to ensure the best performance and long life of your machine. Please refer to this manual and the engine manufacturer’s owner’s manual for maintenance procedures.

Checking the Engine Oil
Check the engine oil level before each use, or every 10 hours if operated continuously. Check the engine oil level with the engine stopped and in a level position.

1. Remove the oil fill cap/dipstick and wipe it clean with a paper towel (see Figure 5).
2. Insert and remove the oil filler cap/dipstick without screwing it into the oil filler neck, then remove it to check the oil level shown on the dipstick.
3. If the oil level is near or below the lower limit mark on the dipstick, fill to the bottom edge of the oil fill hole with SAE 10-30W engine oil. See the SAE Viscosity Chart for other oil weights and temperatures (see Figure 6). To avoid overfilling or underfilling, be sure the engine is in a level position while adding oil.
4. Reinstall the oil filler cap/dipstick and tighten securely.

Changing the Engine Oil

1. Allow the engine to cool slightly. The engine oil will flow more quickly when still warm. Be careful of draining hot oil.
2. Remove the oil fill cap, invert the power driver and carefully drain the engine oil into an approved container for disposal.
3. Return the power driver to its upright position on a level surface.
4. Some oil will remain in the engine after draining. When refilling with fresh oil, start with about 2 ounces. Slowly add SAE 10-30W engine oil into the oil fill and wait one minute for the oil to settle, then continue filling with oil. Slowly add enough oil to fill to the bottom edge of the oil fill hole (see Figure 5).
5. Replace the dipstick. Be careful not to overfill.

Replacing the Air Cleaner (Model 104369 – Honda Engine)

1. Press the latch tab on the top of the air cleaner cover and remove the cover (see Figure 7).
2. Inspect the air cleaner filter. Clean or replace dirty air filter.
   Always replace damaged air filter. Reinstall the air filter and air cleaner cover.

Replacing the Air Cleaner (Model 103400 – DHT Engine)

1. Loosen the air filter cover latch (see Figure 8).
2. Set the air filter cover aside.
3. Remove the air filter.
4. Carefully clean the air filter with hot water and a mild detergent, squeeze the water out and allow to dry. Soak the filter in fresh oil, squeeze the excess oil out and replace in the filter housing.
5. Re-install the air filter cover.

To avoid personal injury or damage to the engine do not run the engine without an air filter.

Changing/Cleaning the Spark Plug
The recommended spark plug is the correct heat range for normal engine operating temperatures. An incorrect spark plug can cause engine damage.
Recommended Spark Plug: CM5H (NGK), CMR5H (NGK)

1. Remove the hex bolt on top of the engine cover (remove two hex bolts on the top of the cover on the DHT engine model) and slide the cover off (see Figure 9). Disconnect the spark plug cap, and remove any dirt from around the spark plug area. Remove the spark plug with a 5/8-inch spark plug wrench (see Figure 10).

2. Inspect the spark plug. Replace it if damaged or badly fouled, if the sealing washer is in poor condition, or if the electrode is worn. Measure the spark plug electrode gap with a wire-type gauge. For good performance, the spark plug must be properly gapped and free of deposits. Correct the gap, if necessary, by carefully bending the side electrode. Gap should be: 0.60 0.70 mm (0.024 0.028 in)

3. Install the spark plug carefully, by hand, to avoid cross- threading. After the spark plug is seated, tighten with a 5/8-inch spark plug wrench to compress the sealing washer. When installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer.

4. When reinstalling the original spark plug, tighten 1/8 – 1/4 turn after the spark plug seats to compress the washer.  A loose spark plug can overheat and damage the engine. Overtightening the spark plug can damage the threads in
   the cylinder head.

5. Attach the spark plug cap to the spark plug. Reconnect the spark plug cap.

6. Install the top cover, and tighten the 5mm hex bolt securely.

Spark Arrestor Cleaning/Replacement

1. Remove the 5mm hex bolt on top of the engine cover and slide the cover off (see Figure 9).
2. Remove the three 4mm x 6mm self-tapping screws from the spark arrester and remove the spark arrester and the exhaust filter from the muffler (see Figure 11).
3. Pinch the exhaust filter, strike lightly with a finger, and remove carbon deposits. Be careful not to strike strongly. The exhaust filter must be free of breaks and holes. If it is damaged or fouled excessively, replace with a new exhaust filter.
4. Use a brush to remove carbon deposits from the spark arrester screen. Be careful to avoid damaging the screen. The spark arrester must be free of breaks and holes. Replace the spark arrester if it is damaged.
5. Install the exhaust filter and spark arrester in the reverse order of disassembly. When you install the spark arrester, the spark arrester’s outlet must point to the side opposite the spark plug.
6. Replace the engine cover, reinstall the hex bolt and tighten securely.

Crankshaft and Piston Lubrication

1. Remove four hex bolts and crankshaft cover (see Figure 12).

2. Inspect the color and amount of grease inside the crankcase. There should be a ring of grease collected to the wall inside the crankcase. Should the depth of the ring from the wall inward measure 1/4” or less this indicates the grease is low.

3. If the amount of grease is low, add a small amount. The maximum level should not be more than 1/2”.
   NOTE: Overfilling with grease can damage the power driver.

4. If the grease is discolored, clean out old grease and add new grease level with the bottom edge of the crank pin head.

5. Inspect the o-ring seal and replace it on the crankcase cover.

6.  Replace the crankcase cover and tighten the hex bolts.
