Preventive maintenance for forklift
You have a lot of money invested in your forklift. In order to protect that investment, perform preventive maintenance on your forklift regularly. Whether you or someone in your shop is performing your forklift maintenance or if you are having an outside company perform the maintenance on your forklift, it is good to know the procedure to be sure that your forklift is properly maintained.
Start the forklift and let it run briefly while you listen to the engine performance. Listen for any knocks or misses. Listen for any squealing caused by the belts. Then listen for any exhaust leaks. Drive the forklift forwards and backwards to check for any slips and to observe any possible wheel issues. Shut the engine off.
When performing preventative maintenance on your forklift, first check the horn, gauges, safety warning devices, cab lights, outside lights, back-up lights, and overhead guard for proper operation. Check for any burnt out bulbs and if any device still does not work, check the wiring and make repairs.
Next in your forklift preventative maintenance procedure is to check the battery compartment. Clean the battery terminal, battery cables and battery connectors. Open every cell cap and check the cells for proper fill levels and fill with water as needed. Apply protectant on the connectors to prevent corrosion. Leave the battery cables disconnected.
Drain the oil from your forklift. Change the oil filter, change the hydraulic filter, transmission filter, fuel filters, and the air filter. Prior to installing the new filters, use a permanent marker to write the date on the new filter. Check all fluid levels and fill as necessary. Check the anti-freeze in the cooling system.
Visually inspect the drive axle when you are underneath the machine. If there is a grease fitting, make sure to grease the drive axle.
Check the belts on the forklift engine. Check for cracks and frays on the belts.
Perform a visual check of the forklift's exhaust system. Look for any cracks or holes in the exhaust system.
Look at the tires on the forklift for any cracks or signs of excessive wear. On an air filled tire, check the tread. Check the differential fluid.
Check the clutch pedal on your forklift. Check the steering cylinder and the drag links. Check for any leaks or for any bends in the system.
Proceed to the hoist and look at the hydraulic lines for any leaks. If there are any leaks on the hydraulic system of your forklift, tighten the lines. If this does not correct the leaks, the fittings may need to be changed or an o-ring may need to be replaced.
While inspecting the hoist, look at the forks and mast to see if there are any visible cracks or chips. Look for any bowing or bends in the forks. Any of these should be noted on your checklist and flagged to the owner and operator as a potentially dangerous issue which needs to be further addressed.
Lubricate all the fittings on your forklift. This would include the hoist mechanism and tie-rod ends.
Checking the wheel bearings is listed on preventative maintenance checklists. However, this is normally done when replacing the brakes on the forklift. Unless there is some indication during the initial driving check out of the forklift that there may be an issue with the wheel bearings, it is not recommended to check the wheel bearings. More harm than good may be done when checking the wheel bearings.
Reconnect the battery cables and start the forklift again. Listen again for any unusual noises.
Lastly, a good preventative maintenance on your forklift will include some cleaning. Wipe down the forklift and use a spray cleaner to clean the forklift. Jeff recommends an oil based spray cleaner for the most effective cleaning of your forklift.
Always follow proper safety procedures when performing any maintenance on your forklift.

SHAFT ALIGNMENT
Misalignment is a common and sometimes serious problem.Poor alignment can cause premature wear or failure of bearings,overheating of shaft couplings,and,in extreme cases,cracked or broken shafts.The procedure for alignment depends on the type of equipment and its design.
Large vertical units,suspended from a thrust bearing in the motor or generator,require making the shaft plumb and the guide bearings concentric.
The lineshafts of vertical turbine pumps are held in alignment by lineshaft bearings in the pipe column.The proper alignment of the lineshaft depends on the proper assembly of the pipe column and the bearing retainers.Depending on the design,the pump motor to lineshaft coupling may be aligned by the face and rim method or the reverse indicator method.

Turbine and pump maintenance
HYDRAULIC TURBINES.
Hydraulic turbines are classified as either reaction turbines or impulse turbines reffering to the hydraulic action by which the pressure or potential energy is converted to rotating or kinetic energy.The reaction turbines include the francis turbine and the propeller types,while thew impulse turbines are represented by the pelton type turbine.
Impulse turbines convert all available head into kinetic or velocity energy through using contracting nozzles.The jets of water from the nozzles act on the runner buckets to exert a force in the direction of flow.This force or impulse as it is referred to turns the turbine.Impulse turbines primarily are used for heads of 800feet or more although they are also used in some low-head applications.
A propeller turbine is similar in appearance to a boat propeller.Water is directed and controlled in much the same manner as with the francis turbine.A variation of the propeller turbine is the kaplan turbine which features adjustable blades that are pivoted to obtain the highest efficiency possible at any load.

Maintenance Schedules and Documentation
Complete,thorough,and current documentation is essential to an effective maintenance program.Whether you are performing preventive,predictive,or reliability centred maintenance,keeping track of equipment condition and maintenance performed or planned is critical.
Maintenance recommendations contained in this report should be used as the basis for establishing or refining a maintenance schedule.Recommendations can be converted into job plans or work orders in MAXIMO or another maintenance management system.Once these job plans and work orders are established,implementation of well executed predictive or RCM is possible.
The maintenance recordkeeping system must be kept current so that a complete maintenance history of each piece of equipment is available at all times.This is important for planning and conducting an ongoing maintenance program and provides documentation needed for the power O and M reviews.Regular maintenance and emergency maintenance must well be documented,as should special work done during overhauls and replacement.

GENERATOR MAINTENANCE SCHEDULING.
A generator is an electromechanical device that converts mechanical energy to useful electrical. Generators varies in sizes and also varies in the power it generates.We also have the sound proof generators which reduces the noise to a low decibel of sound. The diesel generator is an example of critical equipments which needs to be maintained adequately for effective systems reliability.The basic preventive maintenance for the diesel generator is to service the generator every 250 hours of operation.

WHAT IS A VAPOUR COMPRESSION REFRIGERATION SYSTEM?
A vapour compression refrigerating system is an improved type of air refrigeration system in which a suitable working substance termed refrigerant is used.It condenses and evaporates at temperatures and pressures close to the atmospheric conditions.The refrigerants usually used for this purposes are ammonia,Carbon dioxide and sulphur dioxide.The refrigerant used does not leave the system but is circulated throughout the system.
TROUBLESHOOTING TECHNIQUES.
The first thing to check for is refrigerant leakages
Secondly check if the compressors,condensers and evaporators are working.

WHAT IS INTERNAL COMBUSTION ENGINES?
Internal combustion engines are engines in which the combustion of air-fuel mixture takes place internally i.e in d combustion chamber.examples are the diesel generator,forklift engines.e.t.c.Troubleshooting is when a maintenance engineer or technician is trying to get a particular area where the problem is occuring.Troubleshooting requires the technical know how of the maintenance engineer. The first step to take when troubleshooting is to release air trapped in the combustion chamber.Second step is to check the airfilter,fuelfilter,battery terminals,oil filter.
