It wont hammer when I put a small or large amount of pressure on the hammer. It hammer only a short while when I start the mammer (about 1 second) and the same when I release the button.

Is there a surge tank installed? If so the bladder might have failed. Put a gauge on it and see what the pressures are in relation to the pump operation.

If you are drilling in masonry with a masonry bit you don't need to have the hammer function on
Just put it on reg drill and just apply a little pressure you will start to see dust come up when you have applied the correct amount.

Have a Great Day.

Hi, the flywheel should be held on with a large nut to the crankshaft.
You need to loosen the nut but DO NOT REMOVE the nut. The crankshaft should have a small amount of back and for movement, place a lever behind the flywheel and apply pressure to the lever in the direction of the nut, I.E. away from the body of the engine. Using a soft hammer (copper) give the nut a solid hit, this should dislodge the F/w off its taper.

empty the old fuel, replace it with new, spray a small amount of carb cleaner in the carb as you try and start it,, if this doesn't work, a short blast of starting fluid, but don't do that too often. once the fuel works its way into the motor, you should be ok

Pour a large amount of carb cleaner into the gas tank
With choke on full, pull cord often to work carb cleaner into carb and then let it sit for a day or four.
Your carb is dirty for sure.
The venturi and jets are so small on these carbs that they are easily clogged with gunk from old gas

I always where possible dismantle new and sometimes older small power tools with gear boxes and replace or add to the grease with Molybdenum disulfide grease which reduces the friction a surprisingly large amount therefore increasing the available power at the tool tip and extending the life of the tool by a insignificant amount .
It is particularly noticeable in my Bosch jig saw.

Fuel injected? You may have to remove the air cleaner and put a small amount of gas into the intake manually. Or worse case scenario, the fuel pump has quit because you ran out of gas. They really depend on fuel to keep them cool, and will overheat quickly.

the clicks are a signature of a bad battery, since your is new, it probally is not bad, i would try to jump the car with cables, even though your battery is new, you dont know how long is sat ont he shelf before you took it home, may be weak, 1 good jump to get the motor going and the alternator will charge it right up so wont have to so it again....

the only other thing is the starting system left to look at if that dont work is the starter, try banging on it a little with a hammer, not to hard though, as someone turns the key, this will sometime free up a locked up solinoid.


Good Luck

We use the both the 425 and 475 solo sprayers most days at work and when they start to lose pressure ( after 6 months of daily professional use) we purchase a complete seal kit and put it through them. The only part I can't work out how to remove is the inside cylinder, other than that everything else is easily removed and replaced.

if the wash cycle runs ok then unlikely to be the drain pump or hoses. put drain hose into a bucket and check waster comes out during dry - it wont be large amounts of water. can you hear the drain pump running during the dry cycle?
