Finally, even though the tile cement (mortar) I had chosen was a good one and guaranteed curing during cold weather, it still took longer to cure because of the temperature, which made the job even longer to complete. Although this allowed for laying more tiles, between the weather problems, lighting issues etc., I found myself running out of time necessary for the jog at hand.
Almost any tool is available now as a cordless or battery operated model; with the improvements in batteries that have been made over the past decade, there is really no need now to use tools with cords that just get in the way and can be dangerous hazards. NiCads and lithiums are the most popular with lithium taking the lead and being the primary battery being manufactured fo most tools now. The main complaint with lithiums is that when they run out of power the just stop with no warning. Some of the manufacturers like DeWalt have started to address this issue by adding battery fuel gauge indicators to give the operator an idea of how the battery is powering down; not all batteries have this feature yet. Some of the companies have made huge strides in how the batteries charge. For example, Makita has a built-in shock absorbing feature and a built-in memory chip in the battery to communicate with the Optimum Charger to allow for a more efficient charge during the charging process to optimize the battery's life by actively controlling the current, voltage, and temperature; the charger has a built-in fan to cool the battery to increase the battery's life. One point to note when using these newer lithium batteries is if they become extremely hot, allow them to cool back down, and watch out that they do not get so hot that they explode.
Other considerations when choosing the appropriate tool to use include the power source and the speed specification. Different tools use different power sources such as electricity, battery or fuel and hence the proper tool should be selected depending on the available power source. Different machines operate at different speeds depending on the work they are designed to perform for example a combination hammer has a high speed that delivers a high impact force and is ideal for chiseling or drilling in hard concrete walls.
Another example are saws. There are many types like circular saws, reciprocating saws, jig saws, band saws, cut-out tools, multi-tools, and chain saws to choose from depending on your needs. Here again there is a saw that fits the needs of different situations. If you use the proper one for the job, you will spend less time on the job and not have to do more work to clean a rough job up afterwards. Believe it or not I have seen some folks do demolition work with a chain saw and ruin the chain when it hit nails, whereas, a reciprocating saw with the right blade would cut through that like butter.
Before using any power tool, wear safety goggles or safety glasses with shields which have been approved nationally. If there are many wood chips or dusty conditions, make sure you wear a dust mask. If you are working in a noisy environment, wear ear protection such as ear plugs. Those using power tools should refrain from wearing loose clothing or any dangling jewelry that can catch on the tool. Make sure your hair is tied back and does not interfere with the power tools.
