Truckmount Maintenance: The ICS Q&A
by Jeffrey Stouffer
January 13, 2012
For many carpet cleaning professionals, few investments have
the potential to have the impact – either good or bad – on the bottom line like
a truckmount. Buying a unit can run in the tens of thousands of dollars, but also
have the potential to help their owner make that back twenty times over. It’s
curious, then, why something as simple and obvious as maintenance is so often
overlooked, pushed aside or even ignored completely.
To try and get a
better understanding of why this phenomenon occurs – and how to avoid it – ICS
asked three experts in the field – HydraMaster’s Dennis Russell,
Prochem/Century 400’s Jerry Mckillip and Interlink Supply’s Rick McDonald –
about maintenance, troubleshooting, what constitutes a red flag and more.
ICS Cleaning Specialist: Like any piece of machinery,
truckmounts require maintenance to keep them operating at peak performance.
What are some of the most common maintenance issues you see that operators
should be aware of, issues that, if left unattended, could put their machine
out of commission?
Dennis Russell: Following the recommended oil change service
intervals on the engine, blower and high pressure pump; keeping accurate
service records if customer is doing their own service, and rinsing out tanks
and maintaining filters and filter baskets in recovery tanks to protect the
blower and any downstream heat exchangers from sludge and debris.
Jerry Mckillip: The most common problem I see is also the
easiest to prevent. Make sure all fluids are maintained at the proper levels
and changed when recommended by the truckmount manufacture. Checking the fluid
levels only takes a couple of minutes but is often over looked. There are three
major components, engine, water pump, and blower that need the lubrication
checked, at least weekly, most manufacturers recommended daily. I will be the
first to admit I do not raise the hood of my truck and check the oil every
morning before going to work; however, I do normally check all my fluid levels
on the weekend, it only takes a few minutes. For more information on how to
check fluid level and how lubrications should be changed refer to the
truckmount operator’s manual for recommendations.
Rick McDonald: Most breakdowns, lower water pressure, lower
water temperature, low vacuum pressure and equipment failures are caused by
lack of or improper performed maintenance. For example, low/dirty engine oil
causing breakdowns, damage and reduced engine life; low/dirty/or lack of
lubrication for the blower causing seizing and damage to the blower, coupler,
belts and engine. Low or dirty oil in the high pressure water pump can cause
low pressure, breakdowns and damage. Dirty filters (engine air filter, waste
tank filters, water system filters etc.) cause breakdowns, damage and premature
failure of expensive components. Water systems full of hard water deposits
causing plugged heat exchangers, diminished water pressure, low water
temperature and premature system damage. And cracked or stretched belts are
always causing breakdowns.
ICS: To borrow from the phrase “an ounce of prevention
equals a pound of cure,” how important is it for operators to follow a regular
maintenance schedule?
RM: To protect the significant investment and provide
maximum dependable life; proper, timely maintenance is critical. All the
equipment a cleaner uses needs some form of maintenance; truckmounts expecially
need daily maintenance performed by the owner/operator and required hourly
maintenance performed by trained and experienced professional service
technicians. Following the manufacturer’s maintenance schedule can help extend
a truckmount’s usable/dependable life by as much as 2 to 3 times beyond those
truckmounts receiving inadequate maintenance, and can save potentially
thousands of dollars in fuel costs plus help prevent the loss of income and
clients caused by on the job breakdowns.
DR: In setting up the customer for success, the end user
needs to have a hands-on training session when he takes delivery of the new
machine. There needs to be education provided for the required service and
service intervals; and following the schedule and documenting these intervals
as required by the manufacturer is the “ounce of prevention” that is
critical.
JM: Early detection is the key, following a well planned
maintenance schedule is essential to keeping the unit in good operating
condition. To borrow another phrase “schedule your maintenance or it will
schedule you!” Think about it: balance
the cost of being down with the cost of preventing down time. Smart businessmen
schedule maintenance as they do customer appointments.
ICS: What’s the easiest problem or issue for operators to
avoid when it comes to maintaining their truckmount?
JM: Know the truckmount you are operating. All of us may not
be mechanics and have the desire to work on truckmounts, however, when you
operate the same truckmount each day you get familiar with how that truckmount
works and also know how to check the fluids. I think in many cases maintenance
items are overlooked simply because the operator does not know how or what to
do. Even if you are not going to perform
the maintenance on the truckmount you need to know the basics, how to check the
truckmount for fluid levels and what to do if they are not correct. I often get
calls from operators, that don’t know what to do if they see a coolant overflow
bottle empty, or know how long it has been empty. It’s OK if you don’t want to
change oil in your truckmount but you need to know when something is wrong,
start with reading the owner’s manual and if you have questions check with your
local dealer.
DR: Read the owner’s manual! Ask questions and take
ownership of service on this new piece of equipment. Finally, follow all
recommended service requirements, don’t skip or skimp.
RM: Equipment breakdowns on the job – poor dependability.
Performance and efficiency issues – a properly maintained truckmount will
perform all the tasks it was built for at peak performance and efficiency,
which result in cleaner/dryer carpets and surfaces and happier home and
business owners. High fuel costs: A properly maintained truckmount will burn as
much as 25% less fuel compared to a under-maintained truckmount.
Ensure maintenance is done consistently and done right –
daily inspection and maintenance is critical, plus it’s extremely important to
provide routine maintenance at the proper hour intervals, i.e. 100 hours, 200
hours etc. Hourly maintenances should be performed by professionals who are
trained and experienced with truckmounts.
ICS: What’s the biggest misconception cleaners have when it
comes to truckmount maintenance, e.g. “It’s going to cost me an arm and a leg”
“Another couple hundred hours won’t hurt anything” “Just throw a little duct
tape on it, it’ll be fine”?
RM: “I own a ‘SUPER TRUCKMOUNT,’ it’ll be OK if my equipment
gets maintenance when I can get around to it. My truckmount will be fine even
if I sometimes or regularly miss the daily maintenance or skip the proper
hourly maintenance.” On the contrary, truckmounts run at nearly maximum load capacity
under adverse conditions – extreme heat or cold, limited air flow, dirty/dusty
conditions etc., proper and timely maintenance is critical.
There are some who believe that changing the truckmount
engine oil and filter constitutes “proper maintenance.” Truckmounts are complex
machines with many components and assemblies all requiring proper and timely
maintenance. Then there’s “professionals charge too much for equipment
maintenance.” The opposite applies, maintenance costs are a fraction of the
costs of major component repair or replacement.
DR: “The pain of a poorly maintained machine far outweighs
the joy of not maintaining it regularly by the book”. Cutting corners in
servicing a piece of equipment will cost you more in the end. The old sayings
hold true: “pay me now or pay me later” and “penny wise, pound foolish.” You
are making your livelihood on this machine, why skimp?
JM: I once heard “you can pay now or you can pay later.” I
will admit the old duct tape may get you through the job but you had better
take care of the problem or it will shut you down next time. Many times the
problem starts out small a little leaking oil maybe a small water leak, if
taken care of it may not be too costly, let it go and it will only get worse.
Take a blower with a
small oil leak, it may start out small and the operator just keeps adding
oil and maybe put a little extra oil
just in case. That’s all well a good until, you forget to top the oil off and
it runs dry or that little extra oil that is added may overfill the crankcase.
When a crankcase is overfilled the oil will foam and will lose the lubrication
quality and before you know it your blower has to be replaced because of a
small oil leak. It is far too costly to ignore or band aid the small problems.
ICS: What’s the one thing an operator should never ignore
when it comes to maintenance signs/signals/indicators?
DR: Daily maintenance. Checking oil levels and coolant
levels on all components, and dumping the water from and cleaning the waste
tank. Any smells, unusual odors or noises coming from the truckmount, or
leaking fluids, oils, coolants, waste water? Get that looked at ASAP.
JM: If the truckmount has warning lights don’t ignore them,
problems don’t fix themselves. This also goes back to knowing your equipment,
if you hear a new noise or the engine is not running properly shut it down and
get it checked out, the longer it runs the more damage can happen.
RM: First, NEVER start the truckmount until the pre-startup
maintenance checks have been completed! Then look and listen for any unusual
performance. For instance, is it hard to start? Does it run different or sound
different? Is there unexpected water pressure, water temperature, suction,
chemical flow, etc.? Are there fluid leaks? Is it smoking, or is there an
unusual smell?
