Hello everyone, What is a general cost for maintence on a machine for a 40 hour work week per 100.00 dollars made...

Like unloaders,seals,coil descaling,and general type repairs over time...

My machine is new and I dont have a good grasp at what this stuff will start to run me or how much I should put away per 100.00 made in this business... Lets talk 3,000 psi at 5 gpm machines...

thanks for your time....

some people can tell you what they pay but you could be way diffrent then them.
You water could be harder or softer[descaling]
You might treat your unloader like gold,they might have employee's that let let them run a lot in bypass. You might have your unloader left the way it comes, others may route the return to the supply tank. This will in return save your unloader and the packings in your pump.
So you can see that equipment set-up has a lot to do with cost's.
I think on my next unit im going to get the clutch system add-on.
No unloader. When you pull the trigger the clutch engages and the engine revs. When you let go the engine returns to idle and the clutch disengages the pump. This should make your equipment last a lot longer but it is also more stuff to breakdown. We will see.
Dont forget the replacement cost of the whole unit. I add that cost to the week also.
My way it's 10% for maint and replacement/upgrade but that inc tips,o rings,ect....
 
Hi Matt,


You'd probably be better off to figure maintenance based on hours billed, that your machine is running. It's fairly unlikely that your machine will run 40 hours a week, it only sounds like that. It's a safe bet that if you guesstimated gas, oil, diesel, air filters, oil filters, etc. which we consider as maintenance items you're looking at about $2500 per year and that's probably for about 1000 hours of usage (which is on the high side if you are starting out). As you know when you do hoods your machine isn't running the whole time. We consider unloaders, descaling, etc in the repair category around $500.00 per year. Pre-purchasing them(hoses, O rings, filters, Q.C.s, etc.) for later usage as Shop supplies at $500.00 per year. Also take into account, equipment depreciation at $250.00 per year plus equipment replacement at $1000 per year for pumps, engines, spinners, etc. By the way, these items are all billed to the job in the hourly pricing structure, which means they add up to $4750.00 / 1000 hours or $4.75 a billable hour. If you want a 20% profit for growth it's $4.75 / 80% or $5.94 per billable hour. That's how the business pays for it. Hope that helps.


good luck

I have two questions pertaining to clutch systems and re-routing the return to the tank...First, I'm new to my equipment, and don't know if I have a clutch system or not. When I pull the trigger on the gun, I don't get pressure right away, which is different from the cold water machines I'm used to. Any idea why this is? Is this the result of a clutch?

Also, what exactly is the benefit of re-routing the return to the tank, and if there is substantial benefit, then that would mean it is better to run with a tank even if you're not supplying your own water?

Thanks!

you prob. dont have the clutch system. It is an aftermarket add-on and big$$.
The advantage of routeing the water from the unloader to a tank is that when you let off the trigger to water is recircleated into the supply tank and not just a small closed loop.
The pump head will get overheated in a short amount of time if left in bypass if it is not routed to the supply tank. That is why they tell you not to go without pulling the trigger gun every 2 min.
If you route the return to the supply tank you can let your rig run in bypass all day.
Only prob. is you cant have upstream chem if you route it to your tank. It will suck the chem into the fresh water.
Your DE-LAY might be because you are running a diffrent type of unloader then your other unit.
There are pressure type[where you get a kick] and FLOW type[k-7] where there is little kick. You prob. now have a flow type.
 
Yes Ron I agree.

The upstream. Not a problem. I use downstream and re-route the water back to my tank and it is not a problem.

Your maintence cost will vary however. We run soft water only through our machines so we don't get the scaling and the build-up. That alone saves many maintenance cost from the tank to the tip of the wand.

Just my 2 cents.
