Are you operating 24 hrs/day 365 days per year? If so at the end of 5 year term you may very well have many more hours than 10K. In my experience in an average application lift generally accumulate 3-3.5 hrs on the meter per 8 hour works shift in a very high cycle operation (like a bulk break freight terminal - the most I've seen in 401 years in the business) forklfits average about 5.5 hours per 8 hour shift. This means about 16,425 hours in a normal work enviroment 7day/24 hour work period for 365 days or 30,112 hours in a cycle enviorment. Certainly units with this type of hours are worn out.

If you sign on for a contract that only allows 2000 your per year - overtime charges can be quite significant. Also, get a good look at the full maintenance agreement/contract and see if the monthly charge is for the whole contract period. In the States (the former Colony) most lease and maintenance agreements for a 3 shift operation is 3 years and if high usage (hours/day) the term may be 24 months.
Just food for thought. Read any lease & maintenace agreements with a fine tooth comb & ask questions before you put ink on the line.
